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.
