Performance characteristics of volumetric water meters
Measurement level
Volumetric water meters have a high level of measurement and can generally reach Class C or Class D.
Pressure loss
The pressure loss of a volumetric water meter under overload flow does not exceed 0.1 MPa.
Pressure strength
The volumetric water meter can withstand the pressure test of water pressure 1.6MPa, continuous 15min, water pressure 2.0MPa, continuous 1min.
Media and installation requirements
The volumetric water meter has higher requirements on water quality than the rotor type water meter, and the wear is large. If there is impurity in the water flow, the main piston or the main plate will be blocked, the water supply will stop, and the water quality directly affects its service life. As the amount of wear and leakage increases, the metering performance of the volumetric water meter changes slowly.
Performance comparison
Compared with the rotary vane type(single jet,multi jet ,woltman ) water meter, the volumetric water meter has the advantages of high metering level and good sensitivity, but requires high water quality, complicated structure, and difficulty in manufacturing and maintenance.
