Oval gear meters – for extreme requirements

Oval gear flow meters are a type of positive displacement meter. They are dedicated to measure fluids such as water, coolant, engine and transmission oil or fuel. As liquid flows through the meter, a pair of oval shaped gears are forced to rotate by the flow of the liquid. These gears mesh together & force a finite amount of fluid through the meter. A Hall sensor detects the rotation of the gears to determine the displaced volume of liquid. The faster the flow rate, the faster the gears turn. The resulting pressure loss is very low due to the special tooth geometry. An excellent start-up behaviour allows measurements up to near standstill. Due to their design, oval gear meters measure independently of changes in viscosity or temperature of the process media. The installation is simple and space-saving, as no flow straighteners are required.

Do you need a solution for aggressive media or high static pressures? Upon request, we will be glad to manufacture customer-specific versions. Our team looks forward to your task.
