Positive Displacement (PD) flowmeters are suitable for high viscosity fluid or thick liquids like industrial or hydraulic oils, tar, honey, grease etc. This flowmeter is categorized in different types, like oval meter, gear flowmeter and diaphragm types. Since internal parts move by fluid pressure, the PD meter has a very high accuracy along with high-pressure drop. It is one of the best solutions for high viscosity oil or grease pump stations or anti corrosive injection packages when equipped with a switching module. It is a perfect totalizer device for volume measurement. Metron guarantees providing the best solutions for the similar packages.
