Two meshing gears are rotated by the flow energy of the medium, the amount of liquid is transferred between the housing and flank of tooth. Based on the measured frequency the correct flow rate is de-termined.
By default the GFM are measured and calibrated in flow direction (see label) for mineral oil at 30mm²/s, optionally other calibration viscosi-ties or a calibration in both directions are possible.
