The principle of a gas meter test facility is that a gas meter to be tested (MUT Meter Under Test) is compared with one or more reference meters. The MUT and the reference meters are connected to each other by means of pipes and valves. The installation often has a fan and a control valve which is used to set a certain flow. The whole is constructed in such a way that the same amount of air passes through the MUT as through the reference meters.
When preparing a test, the operator will set a number flow rates with a specific test time. The gas meters emit a number of pulses during the test. The number of pulses per unit of time is a measure of the amount of air that passes through the meter. However, this amount is not only dependent on the number of pulses per unit of time. In determining, the influence of temperature and pressure is also taken into account. In addition, a correction is also made to the deviation of the reference meters at the set flow rate. Ultimately, the amount of air through the MUT is compared with that of the reference meters. A percentage deviation follows from this. Doing this for multiple flow rates, spread between the maximum and minimum capacity creates an error curve. This error curve indicates the quality of the meter to be examined.

FMTB test bench series are compact test benches using air under atmospheric conditions. The test bench is designed to calibrate to a high level of accuracy in the shortest possible test time. The FMTB is equipped with high quality sensors and instruments whose measurement results are traceable to international standards. The FMTB series units are fully automated and by reducing thermal expansion effects, the smart control makes it possible to calibrate meters in a very short time. Using a multi-channel data analyzer with built-in clock it is possible to sample and collect data with a very high accuracy. The Flow setting is performed over a frequency regulated blower in combination with regulation valves that enable fast and accurate flow regulation over a wide range at any set point.
The FMTB is pre-calibrated by FMG and ready for use. It is suitable for calibration of diaphragm meters, rotary gas meters, turbine gas meters and ultrasonic gas meters.
