Recently, Flow Control published a Q&A regarding thermal mass flow measurement after corresponding with Wayne Shannon, Sage Metering Product Marketing Manager. In this Q&A, various topics were tackled, including the technology’s pros and cons, end-user challenges, application acceptability, and installation best practices.

To summarize, here is a reader’s digest version of the Q&A conversation:

Q and A end-user challenges, application acceptability, installation best practices
In a recent Q&A – we discuss the pros and cons of thermal mass flow meters, end-user challenges, application acceptability, installation best practices, and more.

What are the limitations of this flow measurement?

    • Can only measure the gas the manufacturer calibrated the meter
    • Not accurate when measuring wet gas
    • Variability during periods of rapid temperature changes

Which applications are most suitable for thermal flow meters?

Common pitfalls encountered when using thermal flowmeters?

    • End-user overlooks the length of the straight run, which impacts the flow profile
    • The flow profile in the installation must be the same as the calibration flow profile

Critical challenges for using thermal flow meters in flare gas measurement?

How can an end-user ensure the meter best matches the needs of the application?

    • Provide the flow meter manufacturer the ranges of flow rate and temperatures, pressure, gas composition, and piping system description, including pipe’s straight run and disturbances.

For a further explanation on any of these questions, as well as a glimpse of what the future technology holds, read “All You Ever Wanted to Know about Thermal Flow Meters.” Additionally, our article, “How to Overcome Thermal Flow Meter Limitations,” tackles nine thermal flow meters’ limitations and how to address them.
