Positive displacement flow meter, also known as fixed displacement flowmeter, referred to as PD flowmeter (positive displacement meter), is the most accurate type of flow meter.
It is a type with high precision in the flow meter, especially suitable for the measurement of the flow rate of high viscosity medium.

 

The oval gear flowmeter uses a mechanical measuring element to continuously divide the fluid into a single known volume part, and measures the total volume of the fluid according
to the number of times the metering chamber is filled and discharged successively and repeatedly.

 

It is especially suitable for flow measurement of heavy oil, polyvinyl alcohol, resin and other media with high viscosity.

 

 

Oval gear flow meter (also known as displacement flowmeter, gear flowmeter) is a kind of positive displacement flowmeter, and it is a kind of high precision flow meter.

Accuracy: 0.5%

 

 

The measuring part of the oval gear flowmeter is mainly composed of two intermeshing oval gears and their housing (measurement chamber)

The metering chamber is filled successively and repeatedly Discharge amount + discharge times to measure the total amount of fluid volume

(The volume of displacement flowmeter displacement is also equal to mass)

 

 

 

Classification of positive displacement flowmeter

Volumetric flowmeters are classified according to their measuring elements and can be divided into

Oval Gear Flow Meter

Scraper flowmeter

Dual Rotameter

Rotary Piston Flow Meter

Reciprocating piston flow meter

Disc flow meter

Liquid-sealed rotary drum flowmeter

Wet gas meters and membrane gas meters, etc.
