Thermal mass flow measurement instruments are typically separated into two main categories: Mass Flow Meters and Mass Flow Controllers. It’s estimated that over 90% of mass flow measurement instruments sold are mass flow controllers. So, it’s no surprise that most mass flow application conversations focus on mass flow controllers. Notwithstanding, there are still numerous applications for which mass flow meters are critical.

The following are common applications for mass flow meters (also known as thermal mass flow meters):

One popular application for mass flow meters is leak testing. It’s often used on products where failure is not an option. For that reason, it is widely accepted in the aerospace, automotive, and medical industries. High throughput leak detection using mass flow meters is a nondestructive testing method that offers a fast, clean, precise, and affordable solution for parts manufacturers seeking to perform leak testing on 100% of their products.

A typical test stand is shown in Figure 1. For high throughput leak detection, a pressurized manifold has multiple connections for mass flow meters. On the outlet side of each flow meter is an isolation valve and the test part. When the isolation valve is opened, test part leaks will be noted by the movement of clean dry air across the flow meter. The test part is only exposed to clean dry air.

How does leak detection with mass flow meters compare to alternative methods? It’s faster than pressure decay testing and helium leak detectors. It’s also cleaner than hydrotesting, bubble testing, and liquid penetrate testing.

Frequently Asked Questions (FAQS)

Q: What’s the difference between a thermal mass flow meter and mass flow controller?

A: A thermal mass flow meter measures flow using a thermal flow sensor but does not include a proportional control valve and does not control gas flow. While a thermal mass flow controller will both measure and control gas flow, according to a command signal (setpoint). For accurate flow control, the controller measures and adjusts the gas flow using a precise, proportional control valve to maintain stable control of the flow rate based on the readings from the heated sensor.

Q: Are thermal flow meters gas specific?

A: A thermal mass flow meter is built for a user’s specific operating conditions. Teledyne Hastings' thermal flow meters are thermal based, so measurements are gas specific. For example, there would be a difference in heat conductivity between natural gas vs compressed air. Our thermal mass flow meters are built to cover a user's flow range and gas type. 

​Q: What does SCCM stand for?

A: SCCM stands for Standard Cubic Centimeters per Minute. This is a unit of measure for gas molecular flow rate (often referred to as mass flow). In standardized volumetric flow units, the reference conditions, or “STP" temperature and pressure, define the amount of gas by determining the number of gas molecules using the Ideal Gas Law.

Time for another blog in our “Employee Spotlight Series.” This time we will meet Rob Milversted. Rob has worked for Teledyne for over 20 years, and he is the Director of Sales for Process Instruments and Systems (Teledyne Hastings Instruments and Teledyne Analytical Instruments).

Let’s ask Rob some questions and get to know him better.

Tell us a little about your background.

I’m a SoCal boy. I’ve lived most of my life in Chino. I attended Cal Poly Pomona and studied Electrical Engineering as an undergrad. I was always shocking myself with things around the house a as kid, so Electrical Engineering just seemed right.

Tell us about your start at Teledyne.

I got a job as an Electrical Engineering Intern at Teledyne Analytical Instruments (TAI) while still in college. In 2002, I was able to join Teledyne full time as an Electrical Engineer. Teledyne allowed me to complete my MBA (also at Cal Poly) while working. I shifted to sales and held multiple sales and sales management positions. In 2021, I was promoted to Director of Worldwide Sales for Teledyne Analytical Instruments and Teledyne Monitor Labs. In 2023, I became Director of Sales for Process Instruments and Systems (Teledyne Hastings Instruments and Teledyne Analytical Instruments).

What is your current role at Teledyne?

As Director of Sales, I have global product sales responsibility for TAI and THI products. I oversee Regional Sales Managers in North America, and I share sales responsibility with our Directors of Sales in APAC and EMEA.

Outside of work, what do you like to do?

I spend lots of time getting my three kids to extracurricular activities. There’s not much free time. My family is heavily involved in Girl Scouts and Boy Scouts. We do a lot of camping. I also enjoy catching NFL games when I can.

What is your favorite thing about working at Teledyne?

The best thing about Teledyne are the people that work here. Everyone I know works extremely hard and wants to help customers. Everyone is like family. I now meet coworkers from other parts of Teledyne, and I wish I’d met them sooner.

Check out more from our blog and read more about our vacuum gauges and mass flow meters and mass flow controllers (and be on the look out for future postings about Teledyne Hastings' employees.) 

The HVG-2020B wide range, dual sensor vacuum gauge takes measurement to the next level. With a Piezo based sensor and a thermal based Pirani sensor, it accurately and confidently measures pressures across seven decades. The Piezo sensor is media isolated, gas composition independent, and periodically zeroed by the Pirani sensor. An ambient thermal sensor enables the instrument to adjust for temperature and therefore better accuracy.

The HVG-2020B offers multiple linear and logarithmic analog output signal options.

Why do you think we offer so many logarithmic output options?

The linear output may not always be useful. Remember: the HVG-2020B is a wide range gauge that covers seven (7) decades of vacuum. That’s a huge range to cover with a linear output signal!

For example, if you are using 0 – 10 VDC Linear Output:

• At 1000 Torr, the output will be 10 VDC
• At 760 Torr, output will be 7.60 VDC
• But at 1 mTorr, voltage output will only be: 0.00001 VDC

We offer the logarithmic output options to provide better resolution throughout the curve.

Our default output option (recommended option) is the Logarithmic Option (08): 2 – 9 VDC (1 VDC / decade)

If you read Voltage (V), you can quickly calculate Pressure (P):

P = 10^{(V_out - 6)}

Complete linear and logarithmic output options for the HVG-2020B include:

There are analog output signal options to match most common pirani vacuum gauge outputs as well as a non-linear curve based on convection style vacuum gauges. It is also possible to generate a custom user-defined logarithmic output (see section 5.2.8 of the manual).

In addition, the HVG-2020B offers an optional color touchscreen display, free Windows data acquisition software, and a variety of digital communication paths that make the HVG-2020B flexible and user friendly. Whether you need USB, RS 232, RS 485, linear or log outputs, graphical displays for data acquisition logging, this wide range gauge can perform.

You can request the software from our website. Please find the link here: https://www.teledyne-hi.com/resource-center/software

In addition to the windows software, we also have a certified LabVIEW driver.

When selecting a flow meter or flow controller for gases, it is important to understand the difference between the mass flow rate and volumetric flow rate. Unlike liquids, gases do not have a constant volume. The volume of a gas changes as the temperature and pressure change.

Referencing the Ideal Gas Law: PV=nRT

• When the temperature of a gas increases, the volume increases.
• When the temperature of a gas decreases, the volume decreases.
• When the pressure of a gas increases, the volume decreases.
• When the pressure of a gas decreases, the volume increases.

When you only know the volume or volumetric flow rate of a gas, you may not actually know how much gas you have. In this blog, we compare mass flow rate vs volumetric flow rate, how each are measured, and the advantages of each.

What is Mass Flow?

Hastings’ first thermal mass flow meter was introduced in the 1960s, and the phrase “mass flow” has been commonly used. However, the phrase “mass flow” is a bit of a misnomer. Thermal mass flow meters actually measure the flow rate of gas molecules or the molecular flow rate. Since the mass flow meter or controller measures the molecular flow rate, it is independent of temperature and pressure changes. It is not necessary to separately measure temperature and pressure, and temperature and pressure corrections are not required.

Teledyne Hastings Instruments mass flow meters and mass flow controllers use a thermal flow sensor to measure the molecular flow rate. The flow sensor is heated, and the flowing gas molecules transfer or “carry” the heat downstream. The rate of heat transfer is proportional to the mass / number of gas molecules flowing through the sensor which is used to determine the flow measurements.

Mass flow rates can be expressed in true mass flow units such as LB/hr, Kg/hr, and g/sec. However, they can also be expressed in standard volumetric flow rates such as SCCM, SLM, and SCFM. Standard volumetric flow units look like volumetric flow units, but they are mass flow units. Standard units are referenced to Standard Temperature and Pressure (STP). STP must always be defined. Teledyne Hastings Instruments typically uses STP: 0° C & 760 Torr; however, other STPs can be specified.

What Should Mass Flow Rate be Used For?

Mass flow rate measurement is ideal for any application where gas measurement is critical. As stated earlier, there is no need to simultaneously measure gas temperature and gas pressure which can introduce errors to your calculations. It’s ideal for applications requiring fast, reliable, repeatable, and accurate measurements.

Some common applications include instrument calibration, air sampling, non-destructive leak testing, gas blending (mixing), thermal spraying, thin film deposition, analytical instrumentation, and many more.

What is Volumetric Flow?

Volumetric flow rate is mathematically defined as the cross-sectional area of a tube multiplied by the velocity of the fluid. It simply measures volume per unit of time. Volumetric flow is ideal for liquids since their volume mostly cannot change. When using volumetric flow meters for gas measurement, the only way to determine how much gas is flowing is to calculate it. That requires either maintaining constant temperature and pressure or simultaneously measuring them. Examples of volumetric flow methods include rotameters, turbine meters, and critical orifices.

One of the most common volumetric flow meters is a rotameter or variable-area flow meter. It consists of a tapered tube and a float. The tapered tube is typically constructed of glass to allow the user to visually see the float. As the flow rate increases, the float travels up the tapered tube. The tube has graduated lines to indicate the volumetric flow rate.

Some common volumetric flow units are GPM, L/s, and CFM. Mass flow can be calculated from volumetric flow only if the density (ρ) is known. Q_mass = Q_vol*ρ.

What Should Volumetric Flow Rate be Used For?

Volumetric flow rates are fine in applications where the volume is constant such as incompressible liquids. They can also be found in gas applications where the temperature and pressure are fixed. In addition, volumetric flow meters typically have a lower initial cost than a mass flow meter. They are often found in low-cost gas measurement applications where molecular flow rate accuracy is not critical. When molecular flow rate accuracy is required, the user typically measures temperature and pressure separately and calculates it.

Summary

Both mass flow meters and volumetric flow meters are commonly used to measure gas and liquid flow measurements. For gas flow measurement, mass flow is more trusted as it measures the gas molecular flow rate. Mass flow meters and controllers function independently of gas temperature and gas pressure changes. This makes mass flow meters and controllers ideal for applications requiring fast, reliable, repeatable, and accurate measurements. Volumetric flow meters such as rotameters or critical orifice devices cannot routinely achieve these high accuracy levels on gases due to inherent inaccuracies and variations that occur as a result of pressure and temperature changes.

FAQS

• Q: Can Teledyne Hastings’ flow meters be used with liquids or any fluid?  
  A: No. Teledyne Hastings’ flow meters cannot be used with liquids. A fluid is defined as “a substance without a shape and can be either a gas or liquid”. Fluids used in our flow meters must be in the gas phase (gases only).

• Q: What is STP (Standard Temperature and Pressure)?
  A: In standardized volumetric flow units (SCCM, SLM, SCFM), the reference conditions, or “STP” temperature and pressure, define the amount of gas by determining the number of molecules using the Ideal Gas Law. In most cases, the selected reference conditions are 0°C & 760 Torr. Other reference conditions are also used, such as 20°C & 760 Torr, or 70°F & 760 Torr.

• Q: What does SCCM stand for?
  A: SCCM stands for Standard Cubic Centimeters per Minute. This is a unit of measure for volumetric flow. In standardized volumetric flow units, the reference conditions, or “STP" temperature and pressure, define the amount of gas by determining the number of gas molecules using the Ideal Gas Law.

Calibration is the cornerstone of measurement accuracy, ensuring that instruments deliver reliable and precise data. Thermal mass flow meters play a pivotal role in providing a dependable solution for various industries. The calibration of these instruments is a critical factor that demands meticulous attention. In this blog, we delve into the intricacies of thermal mass flow calibration, unraveling the science behind it and its significance in achieving accurate measurements.

The Basics: What is Thermal Mass Flow Meter Calibration?

Teledyne Hastings’s flow meters and flow controllers use thermal mass flow sensors. The Teledyne Hastings Instruments 200 Series thermal mass flow meters operate on the principle of heat transfer using thermocouple technology. The flow sensor consists of a capillary tube that is heated at the midpoint. Thermocouples are used to measure the temperature on both the inlet and outlet ends of the tube. As gas molecules travel through the flow sensor, heat is transferred downstream. The temperature differential between inlet and outlet correlates to the molecular flow rate of the gases. The molecular flow rate is directly proportional to the mass flow rate of the fluid. This relationship forms the basis for the calibration process, as accurate calibration ensures that the meter provides reliable measurements across a range of flow rates and conditions.

Calibration is indispensable for maintaining the accuracy and reliability of thermal mass flow meters. Over time, factors such as contamination, sensor degradation, environmental changes, or wear and tear can impact the meter's performance. Calibration allows for the correction of these deviations, ensuring that the meter consistently produces accurate readings. Moreover, many industries are subject to regulatory standards that mandate regular calibration to guarantee the reliability of the data collected.

How To Calibrate Your Mass Flow Meter

1. The first step in thermal mass flow calibration is establishing a reference standard. This is typically a device with a known and traceable accuracy. The reference standard is used to compare and verify the accuracy of the mass flow meter being calibrated. This can be a reference standard or another flow meter. A high accuracy 300 Vue thermal mass flow meter or mass flow controller with local touchscreen display would create a standard that the unit under calibration will match to.
   
   
2. Calibration involves subjecting the flow meter to controlled flow rates covering its entire operating range. The meter's response to these different flow conditions is carefully observed and compared to the reference standard. The best calibration would be used with actual gas to get the most accurate data points. Since the actual gas (e.g. Helium) could be expensive or rare, then a more accessible gas such as N2 or Air is used with a conversion factor to calculate the actual flow rate in the desired gas.
   
   
3. As the flow meter undergoes calibration, data on its performance at various flow rates is collected. This data is then analyzed to identify any deviations from the reference standard. The reference temperature and pressure may differ from the actual process temperature and pressure. Calibration software may be employed to streamline this process.
   
   
4.  If discrepancies are detected, adjustments are made to the thermal mass flow meter to correct its readings. This may involve recalibrating sensor elements or updating compensation factors. The goal is to align the meter's measurements with the reference standard. It is important to note how large these discrepancies are as it may require repair instead of calibration.

In the world of fluid dynamics and process control, selecting the appropriate flow measurement parameter is crucial for accurate and reliable data. Teledyne Hastings’s uses heat transfer technology to indirectly measure the molecular flow rate of dry gases. Our instruments can be used with volumetric flow units as they are converted to find the mass flow rate.

What is the Thermal Mass Flow Meter Working Principle?

Basic Design:

A mass flow meter consists of four basic components:

1. Electronic Circuit Board
2. Flow Sensor
3. Bypass Shunt
4. Base

*See Figure on right

In the world of fluid dynamics and process control, selecting the appropriate flow measurement parameter is crucial for accurate and reliable data. Teledyne Hastings’s uses heat transfer technology to indirectly measure the molecular flow rate of dry gases. Our instruments can be used with volumetric flow units as they are converted to find the mass flow rate.

There are numerous thermal mass flow sensor designs.  The Teledyne Hastings’ 200 Series sensor is shown in image on left.  This thermal mass flow sensor consists of a small 316SS capillary tube with a heater winding located in the center.  A thermocouple (TC-1) is located on the inlet side and another thermocouple (TC-2) is located on the outlet side.  At zero flow (no gas flow), the heat is transferred through the capillary tube in both directions towards the two thermocouples, each of which has the same temperature (see image on right, ZERO FLOW condition).  As gas flow moves through the capillary tube (inlet to outlet), heat is then transferred downstream by the gas molecules.  The temperature of TC-2 will increase, while the temperature of TC-1 will decrease.  This temperature differential correlates to the molecular flow rate of the gases (mass flow). 

Output:

A majority of thermal mass flow meters provide an analog output signal (0-5vdc, 4-20mA, etc.) that is directly proportional to the gas flow rate.  System integrators can directly acquire this signal for process control.  

If the installation is not configured for data acquisition, Teledyne Hastings offers convenient power supplies with integrated displays (see models THCD-101 and THCD-401 in image on right) and ready-to-use connector cables for quick start-up.

Some mass flow meters offer digital communication to convey the flow rate, while other models have a built-in color touchscreen display (See model HFC-D-302B Vue in image on left).​

Thermal Mass Flow Meter Advantages

Thermal mass flow meters have gained widespread popularity in various industries due to their numerous advantages in measuring the flow of gases. Let's explore some of the key advantages of thermal mass flow meters:

One of the primary advantages of thermal mass flow meters is their ability to directly measure mass flow rate. Unlike other flow measurement methods that may require additional measurements or assumptions about fluid properties, thermal mass flow meters provide a direct and accurate measurement of gas flow.

Thermal mass flow meters are less affected by variations in pressure and temperature compared to some other flow measurement technologies. This robustness allows for accurate measurements even in environments where these conditions may fluctuate, reducing the need for extensive compensation or correction factors.

Thermal mass flow meters can be used across a broad range of gas flow applications. They are suitable for measuring the flow of various gases, including compressed air, natural gas, and specialty gases. This versatility makes them valuable in industries such as pharmaceuticals, petrochemicals, automotive, aerospace, and more.

Thermal mass flow meters typically have a low-pressure drop across the sensor, minimizing the impact on the system being measured.

As technology continues to advance, these instruments are likely to play an increasingly integral role in optimizing processes and improving overall efficiency.

Tell us about your start at Teledyne

I have been here since 2015. Prior to Teledyne Hastings, I worked in a similar role at Jefferson Lab (Department of Energy) in nearby Newport News Virginia. I knew a couple of managers that worked at Teledyne and when they told me about the position here, I jumped at the chance to get started.

Many folks here at the plant know you for your drawings.  How did you get involved in art and design?

I started drawing when I was six years old or so. I was an only child and doing art was a way for me to occupy my time. My art projects sort of kept me company. I am self-taught and I always enjoy seeing other things that artists are creating and sometimes, they inspire me.

We have always enjoyed the Holiday Cards you’ve helped to create as well as the giant chalk drawings. Is there a particular art piece that you are most proud of?

After thinking about it, I’m proud of all my works because people were happy with them. But I am working on something new that I’m very proud of because it involves that community that I grew up in.

Here are some examples of the work he has done for Hastings.

What will he draw for us this year?  Put your ideas / suggestions in the comment box below

Whose artwork has had the biggest influence on you?

I grew up watching Hanna-Barbera action cartoons like Johnny-Quest and Space Ghost. When I was a kid, I really hoped to get a job with them. As I got older, I became more into comic books. Jim Lee is still one of my favorites.

What is your favorite part of working here at Teledyne Hastings?

I like the fact that I know everybody here and we have a family environment. I enjoy supporting people and, in my role in the Stockroom, I put my hands on almost everything that comes into the building.

In the second blog of our “Employee Spotlight” series, we focus on one of our engineers, Josh Settle. Josh works to design, test, and implement the electronics for our new products. In addition, he is a valuable resource to our production teams. He is also a member of our Quality System’s Internal Audit Team.

 Let’s ask Joshua some questions to get to know him better.

Let’s start with a history of your time here at Teledyne
I started summer 2014 as an electrical engineering intern. I didn’t know if I would get the internship, so I picked up another part time job as a lifeguard. I landed the internship later and kept working both. I put in 40 hours at Hastings during the week and 10-16 hours at the Mt. Trashmore Family YMCA on the weekend.

At Hastings I really enjoyed the people I worked with (I still do), and I am thankful for the ways they have invested in me (they still do). I interned again summer 2015 and came back month after undergrad to work full-time. My full-time start date was June 6, 2016. I celebrate 7 years with Hastings this summer.

Tell us a little about your educational background
I completed my Bachelor of Science in Electrical Engineering (mathematics minor) Magna Cum Laude from Virginia Tech in May 2016. That autumn, I immediately began working on my Master of Engineering Degree (Electrical and Computer concentration) at Old Dominion University while working full time. I finished my second degree in the spring of 2022. 

As far as concentrations go, I have always enjoyed mathematics for its brutal objectivity, intense precision, and its numerous tools used to help people observe reality and make meaningful changes.

 I also enjoy transmission line theory, an arcane field where material properties, geometry, circuit analysis, and electromagnetics all converge. I’m particularly interested in microstrip line distributed element filters (see the Distributed-element filter Wikipedia page). This subject has interesting applications because of its similarity to traces on a circuit board. As part of my second degree, I developed a python program that calculates the dimensions of one of these filters based on user input frequency characteristics and compared my program to a professional software package.

What do you do here at Teledyne Hastings?
Short Answer: I solve as many problems as I can, learn from failure, and try to acquire useful skills along the way.

Long Answer: I help the engineering department meet long term goals especially with respect to new product development. I also help with production, repair, quality, tooling, and training needs.

I do everything from working on production benches, configuring tests, interpreting data, leading or supporting internal audits, assisting with technical documentation needs (drawings work instructions, procedures), or even being a liaison between multiple departments (production and sales, production and other engineers).

What are some of your outside interests?
I enjoy fitness, videogames, pizza, and red wine (dark, full-bodied, and dry).

Quote that we might use from you?
“Think things through. Consider the extremes. Speak carefully. Challenge your assumptions. Relax, and don’t be afraid to say, “I don’t know” or ask for help.

Teledyne Hastings’ Mass Flow Controllers (MFC) are used in a very wide range of applications in numerous markets. In this blog, we are going to briefly explore the use of Teledyne MFCs to improve the surface properties of certain metals such as steel. Nitriding, in which a nitride layer is added, can also be used on aluminum and titanium.

There are three methods of nitriding: gas nitriding, salt bath nitriding, and plasma nitriding. (“Nitriding”, Wikimedia Foundation, 1/18/2023, https://en.wikipedia.org/wiki/Nitriding ). We are going to focus solely on gas nitriding. In this process, ammonia gas flow can be controlled into a furnace at several hundred degrees Celsius. The furnace is hot, but not so hot as to risk damaging or structurally modifying the part. Now the incoming gas can be controlled using a high-capacity mass flow controller. After the gas is admitted, the ammonia molecules (NH₃) from the gas dissociates into nitrogen and hydrogen at the surface of the part being treated. The monatomic nitrogen can then diffuse into the surface of the part and form a nitride coating layer.

What are some of the benefits of nitriding? First, the treated part will generally have an increased hardness which in turn will give the part improved wear resistance. Also, many parts that have been treated with the nitride process will be less susceptible to corrosion.

There are many types of parts that are given nitride treatment.

• Gears and splines
• Shafts and bearings
• Valve components
• Extrusion dies
• Rollers for continuous crimping

In large furnaces, high flows of ammonia gas are required, and Teledyne is able to supply mass flow controllers that are accurate, stable, and fast. We are ready to help. Contact us and we will help you size a flow controller for your nitride application.

In addition to our analog 200 Series mass flow controllers, we can also provide our Digital 300 Series (“A” and “B” Models) which feature excellent accuracy ± (0.2% full scale + 0.5% of reading) , fast response, and flexibility. “A” models can be built with IP-67 enclosure which offers protection against external dust and liquids. “B” models can be configured with an optional color touchscreen display. Both “A” and “B” models provide digital and analog (0-5 VDC, 0-10 VDC, 0-20 mA, 4-20 mA) input and output. Both have internal totalizer feature so the user can track the total amount of ammonia gas used in a nitride heat treat cycle. Free user software is provided (but is not required) and, for LabVIEW^™ users, free certified drivers are available from ni.com.

If you have a nitride process or any other application that requires precision gas control, we would very much like to hear from you. You can contact us by phone (757-723-6531), email (hastings_instruments@teledyne.com) or via LiveChat at www.teledyne-hi.com  

We are starting a new blog series where we will introduce you to some of the key employees here at Teledyne Hastings. Our first blog in this series will focus on our domestic sales manager, Will Harrison.

In addition to being domestic sales manager, Will works as a sales application engineer ensuring that customers select the best flow or vacuum product for their application/system. Will also works with our USA channel partners and keeps them informed of the latest products and markets for Teledyne Hastings’ products and services. Will has been with Teledyne for over thirty-five years.

 Let’s ask Will some questions to get to know him better.

• How did you start working at Teledyne Hastings? 
  I had a close friend that worked here who mentioned the expanding sales team was looking to hire a new sales application engineer. It seemed to happen very fast … I applied, was interviewed, and was hired in less than two weeks.

• What is a typical day like for you?
  I am always available for customer phone calls. I enjoy hearing about new opportunities or helping customers improve an existing vacuum or flow application. When not on the phone, you might find me generating a quote for a customer or helping out one of our USA sales channel partners. I also travel with our distributors as we look for new opportunities for Teledyne Hastings.

• Let’s follow up on that, where is one of your favorite places where you have for traveled for work?
  The best place I ever traveled was Vancouver BC. Vancouver is a neat place to venture out, see the sites, and enjoy great food. Our distributor drove us up to see Whistler, which was awesome! At the time, that area had a few startup companies focused on the fuel cell industry and our mass flow meters and controllers were enjoying great success.

• Outside of work, what is it that you like to do?
  I like to run and bike when time permits. I like to do half marathons and full marathons. I’ve even completed a full “ironman” triathlon. I also enjoy Old Dominion University (ODU) sports where I got my degree. The Lady Monarchs won back-to-back national titles in women’s basketball (1979, 1980) before the NCAA became involved. The excitement from the crowds at the ODU sporting events is great.
  
  

• What is one part of the job that you find rewarding?
