The RSM200 gas flow meter (RMG Sonic Meter) is based on the innovative ultrasonic transit time difference measurement technology, which has been increasingly replacing turbine meters for high-precision flow measurements of natural gas for several years. The RSM200 is custody transfer approved and allows the determination of operating and standard flow rates with a pressure and temperature measurement.

The RSM200 determines the flow rate, stores it and totals the current totalizer reading. The RSM200 can transmit its values directly via various interfaces (pulse, analog, digital). In addition, the RSM200 offers a full-fledged corrector including pressure and temperature measurement, so that the standard flow rate and standard volume can be determined in addition to the operating flow rate and operating volume. An external corrector is not required. A long-life backup battery ensures operational reliability even in the event of an external power supply failure. Self-sufficient battery operation is possible for the calibration period, i.e. for more than 5 years.
