What is a rotary piston liquid sealed water meter？
Rotary piston water meter is the use of water meter measuring room two end (inlet and outlet) pressure difference. The water flow entry into the water inlet promotes the piston rotation and squeeze the water indoors to the outlet. With the rotation of the piston, the volume of the low pressure end (water outlet) decreases gradually while the volume of the high pressure end (water inlet) increases continuously. The piston rotates for 1 week, that is, squeeze a water outlet with a metering room volume, and push the fork rotation for 1 week through the piston shaft to record the water consumption.
What is rotary piston liquid sealed water meter？
1.High measurement accuracy
Rotary piston water meter is kiln type water meter with high measuring accuracy using the principle of piston rotation.
2.Clear reading
The data is clearly separated from the water and the readings are convenient.
3.Stable performance
The inlet is equipped with a check valve to prevent backflow.
4.Customizable
The surface of the water meter shell can be copper or spray blue paint, stainless steel shell or nylon plastic shell for customers to choose.
5.Convenient installation
It is made of corrosion-resistant, non-toxic and pollution-free quality materials, and can be installed in any position without affecting the accuracy of the water meter.
