<strong>OVZ</strong>4. <strong>Operating</strong> PrincipleThe <strong>OVZ</strong> oval gear meter is a positivedisplacementflow meter. The measuringelement comprises of two toothed precisionoval gears, which are driven by the liquid inletpressure. As the liquid rotates the gears, afixed quantity of liquid is transported throughthe chambers <strong>for</strong> every turn of the oval gearpair. Permanent magnets or stainless steelpins are embedded in the oval gears. Therotary gear motion is converted to a pulsesignal by electrical sensors externally fittedinto the casing. The pulse count is a measureof the flow rate. The signals are evaluated bydownstream electronics (optional).5.
