Volumetric piston water flow meter

Volumetric water meters are more accurate than speed meters. The velocity meter measurement error will have an error of ±2% depending on the fluid velocity, while the volumetric water meter error can be controlled to ±0.5% or lower.

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.volumetric water meter

R160 Class C volumetric water meter

These piston volumetric water meter are a instruments which directly measure the volume of the fluid and divide it into separate volumetric spaces with known volumes. By multiplying the number of gradually filled volume spaces by the volume of each space, we get the value of flow. It is always measured over a period of time, and the result is the value of a unit of volume in a unit of time. Volume flowmeters usually show the total flow through the counter, but also allow the generation of output pulses, each pulse represents a certain volume of fluid. Pulse numbers can be read or transmitted from the local display to the control system.

Volumetric brass Water Meter

The working principle of the volumetric water meter is that under the action of water pressure, water enters the measuring chamber from the lower water inlet, and the rotating piston is rotated around the central axis of the measuring chamber, and water is formed from the inner space of the piston and the wall of the piston and the measuring chamber. The empty space is discharged to the upper water outlet, and the rotation shaft and the fork are connected to the counting mechanism while the piston is rotating. Therefore, the volume flowing through the water meter can be calculated by counting the number of times the piston is rotated. The most important product of the volumetric water meter is a rotary piston type water meter. Rotary piston type water meters are generally small diameter specifications, characterized by high metering grades (up to C and D Class), small flow metering capability, and high sensitivity. At present, it is mainly used for the measurement of pure water in pipelines.
