RM Series Rotary Meters

Positive displacement type meters that use the classic "roots" principle of measurement. They are suitable for Custody Transfer, Fiscal Measurement or Sub-metering. They conform to ANSI B109.3 Specfications and are approved by UL and CSA.

Two counter-rotating impellers spin inside the pressurized, precision machined measuring chamber. The rotation is transmitted via a magnetic couple to the mechanical index. An odometer style index totalizes the raw "uncorrected" volume. This volume can be transmitted via an integrated Low Frequency Pulser to a remote mounted index, PLC or Energy Management System. Instrument Driver versions can be equipped with a PTZ corrector such as the Gas Micro, which compensates for fluctuations in pressure and temperature.
