Intelligent water meter error cause

In the pipeline system, liquid transient flow often occurs, and the flow velocity and pressure of the pipe flow change with time. The variation range depends on the initial flow state of the pipe flow, the characteristics of the pipe system, and the transient formation conditions. Due to the change of the flow rate, a series of sharp hydraulic pressures will be caused to alternately rise and fall. The pipeline will undergo severe vibration and loud sound. This phenomenon is called water hammer phenomenon. In daily life, we often encounter the situation that the water pipe is shaking and making a sound, which is the water hammer phenomenon. This violent shaking will cause the reed switch to be frequently sucked in a short period of time, and a large number of counting pulses are emitted, so that the metering accuracy is greatly reduced. The cause of the water hammer phenomenon is very complicated, and it is related to the friction of the inner wall of the pipe, the pressure of the liquid and the flow velocity of the liquid, and we cannot avoid it.
