Water Meter check Non-return Valve
In the smart water meter installed before the check valve, since the intelligent water meter rotation is due to pressure fluctuations, water is compressed, you can consider the installation of check valve, check valve can play a role in preventing water backflow. In this way, when the pressure rises, the water is compressed, the smart meter produces a positive rotation; when the pressure is reduced, the check valve is automatically closed and the smart meter does not rotate. When the pressure rises again, as long as the pressure is not higher than the check valve pressure, intelligent water meter will not turn again; intelligent water meter rotation is mainly intelligent water meter reciprocating several times to accumulate a lot of water, install the check valve can Reduce the frequency of intelligent water meter rotation, it can be a good solution to the pressure fluctuations caused by intelligent water meter rotation problem. However, due to the higher frequency of residential water consumption, and the smaller fluctuations in pipeline pressure, so check the valve with high sensitivity, higher quality requirements.
