CGR Rotary Gas Meters

CGR40 – CGR100

The rotary gas meters are positive displacement meters, designed to measure quantity of gas, for custody transfer or technical measurement applications. The devices are mainly applied for gas flow ranges from 0.2 up to 650 m3/h, and the pressure range up to 20 bar.

The CGR-FX Meters are applied in measurement systems where high accuracy is required:

Transportation and distribution of natural gas
Primary and secondary measurements
Control metering of natural gas and non aggressive technical gases in industry
Flow Measurement for technical purposes
