How does an
oval gear meter work?
The oval gear meters / oval gear flow meters are direct volume meters. Their measuring element consists of two toothed oval gears. Through this, a certain amount of liquid is transported through the flow meter with each rotation of the oval gears. With each rotation, the oval gears transport four partial volumes (delimited between the oval gear and the measuring chamber). The number of rotations is an exact measure of the volume that has flowed through.
For measurement, the rotary movement of the oval gear wheels is transmitted via magnets to a pulse generator or a display.
