Test and calibration systems for rotary gas meters, turbine gas meters, and ultrasonic gas meters are compact test benches with very low measurement uncertainty. They are designed to perform calibration at high accuracy levels within the shortest test time. Measurement results are sampled and collected with very high accuracy using a multi-channel data analyzer equipped with an internal clock. Flow adjustment is performed using a combination of a frequency-controlled blower device and adjustment valves, providing fast and accurate flow regulation at any set point. Test banks are pre-calibrated and ready for use.
