Working characteristics of positive displacement flowmeter

(1) high measurement accuracy;

(2) Pipe installation conditions have no effect on the measurement accuracy;

(3) Can be used for the measurement of high viscosity liquid;

(4) Wide range;

(5) Direct-reading instrument can directly obtain the total amount without external energy, clear and easy to operate;

(6) Complex structure, large volume;

(7) Not suitable for high and low temperature;

(8) Most meters are only suitable for clean single-phase fluids;

(9) High noise and vibration.
