QG100 series High Pressure Accurate Circular Gear Flowmeters

The GFM flowmeter measuring system works accordingly to the positive displacement principle. The measuring accuracy is largely independent of the fluid viscosity and provides further measuring possibilities with high accuracy vs an axial turbine or similar. Low flow rates are easily measured with this design. The QG range is useful for accurate measurement of pump case drains or leakage flows or example.

ISDS sensor versions provide improved accuracy and increased low end measuring ranges due to the linearisation data within the sensor.
