This series is an intelligent rotary (Roots) gas flow meter for clean gases. A pair of conjugate rotors, kept in correct relative position by precision timing gears, is driven by the differential pressure of the gas; each revolution displaces a fixed volume, giving a direct volumetric measurement.
The integrated flow totalizer measures temperature and pressure and automatically corrects the volume to standard conditions. The meter is mainly used for natural gas custody transfer and for industrial gas consumption metering.
Key features
- Positive displacement measurement, accuracy ±1.0 %, repeatability ±0.2 % or better
- Built-in temperature and pressure sensors with automatic correction to standard volume (20 °C, 101.325 kPa)
- Low start-up flow and wide flow range
- Pulse, 4 to 20 mA and RS485 (Modbus) outputs; IoT remote transmission and prepaid (IC card) options
- Mechanical counter, electronic totalizer or combined mechanical and electronic display
- Aluminium alloy or cast iron housing, aluminium alloy rotors
