What is a piston water meter?
It is a kind of water meter that measures the amount of water flowing through it according to a certain volume. Its characteristics are that the movement of this kind of water meter is different from the traditional speed type water meter and similar to the piston movement. The structure of the movement is very different from that of the traditional speed type water meter. The movement consists of a counting mechanism and a measuring mechanism, and the counting mechanism is composed of a latch, a gear box and a counter.
Advantages of the piston water meter:
1.Accurate measurement
The piston water meter measurement is more accurate than the speed water meter. The speed water meter measuring error will have a ± 2%error depending on the fluid speed, and the piston water meter error can be controlled at a level of ± 0.5%or even lower.
2.Convenient installation
The structure is solid and the appearance is simple. It can be installed in any direction and flexible use.
3.Stable performance
Selection of high quality raw materials, to ensure reliable and stable performance of water meters. Especially in the pipe network with better water quality, the use of the period is longer. The water inlet is equipped with a check valve, which can avoid the backflow phenomenon.
4.Clear reading
The counting mechanism uses special liquid packaging, the readings are clear and the appearance is compact.
