Questions
- Question
- What is the difference between a Gas Mass Flow Meter to a Gas Mass Flow Controller?
- Answer
- The major difference between the GFM and the GFC is the that GFM is just used to measure the flow going through the meter. The GFC has the added feature of a electromagnetic valve to control the flow to a desired set rate. Our newer GFM flowmeters (GFM2, GFM3, and GFM4) have some added features to the base GFM unit, such as optional relays, push button configuration, and pressure and temperature monitoring, respectively.
