Positive Displacement Flow Meter

Oval Wheel Meter

The positive displacement flow meters are direct volume meters and are used in small, medium and large capacity applications. They have the ability to handle a wide range of fluid viscosities with exceptional levels of repeatability and durability.

They do not need any flow conditioning and are ideally suited for flow measurement of diesel, petrol, de-ionized water, DM water. 

Accessories available include:- Strainer, Gas Separators, Flow Rate indicator, Pulse Amplifiers/Scalers/Convertors, Pulse Counters/Totalizers, Batch Controllers, Heat Extension

Each revolution of the oval wheels displaces a precisely known volume of liquid through the meter, from inlet to outlet. The number of inlets is therefore directly proportional to the measured volume. The pulses generated by the pulse transmitter with high pulse resolution are processed in the electronic converter/digital indicator. (Liters/ Cubicmeters/Gallons etc.)
