Processing method of Rotary Volumetric Piston Water Meter installation techniques, characteristics, operation process, working principle and common problems

Volumetric meter is also called the piston type water meter, is a constant flow type water meter. The national standard in the volumetric meter is defined as “installed in the closed pipe, by some to be a water meter chamber volume successive full known and discharge fluid and with fluid driven mechanism.

Rotary Volumetric Piston Water Meter

Volumetric meter with rotary piston type and disc type two series, when the water flow through the meter, the drive piston flow (circleRotating disc) (swing), and a piston cylinder (disk chamber) volume is constant, so, by counting the measured piston rotation mechanism

Turn (disc swing) times, can get through theĀ Rotary Volumetric Piston Water Meter of water.

Product volume type water meter is the main rotary piston type water meter, see figure C.5 and figure C.6 appendix C. At present is mainly used for the measurement of pipeline pure water, water purification water to produce drinking water meter water Limited by Share Ltd Ningbo and Ningbo Donghai instrument channel limited company as the representative, in the water meter diameter is 8, 15 and 20ram. Volumetric meter repair debugging complex, high requirement on quality, used in China has not yet been widely. Under the action of water pressure, water from the lower water inlet into the measurement chamber, center 3 driven rotary piston 7 surround the measurement chamber shaft to rotate, and the water from the piston blank and piston and the measuring chamber wall surface formed by the air flows to the upper outlet, at the same time the piston rotates, connected by a rotating shaft 4 and shifting fork 5 and counting mechanism, so as long as the note of piston rotation times, can flow through the water volume.

Volumetric meter with rotary piston type and Yuan Pan type two series, its principle is, when the water flow through the meter. The drive piston flow (Yuan Pan) rotation (swing), and the piston cylinder (Yuan Pan chambers) volume is constant, so, by counting mechanism measured piston rotation (Yuan Pan wobble) number it can obtain the flow through the water, water meter.

Requirements of installation and operation:

Requirements of installation and operation:

A, flow direction must be with the table on the arrow direction; B, the installation position to avoid pollution and flooding

This table for the Rotary Volumetric Piston Type Plastic Water Meter, the piston principle, through the rotation of the piston to measure the amount of water through the pipe.

Housing for the pressure casting of brass or stainless steel precision casting, internal main parts use of carbon composite materials, the counter is fully enclosed structure, flow into a eight bit digital recording.

Measurement grade this table for the C class, high sensitivity, small starting flow, clear reading, easy to install, without any range limit.

Measurement of the surface is most suitable for direct drinking water.
