The flow sensing technology of electronic water meter is more excellent and advanced. Compared with mechanical water meters, electronic water meters are developing rapidly in the current intelligent water meters. It changes the problem that the error curve of mechanical water meter is difficult to correct and solves the problem of wear in long-term application.
1. Ultrasonic water meter
Due to the time difference caused by the change of speed, ultrasonic water meter is a new type of water meter that analyzes and calculates the effluent flow by detecting the propagation of ultrasonic beam in the downstream and countercurrent of water. The main features of ultrasonic water meter: there are no moving parts in the measuring pipe and the pressure loss is small; Wide measurement range and good small flow detection ability; Almost not affected by water quality, etc.
2. Electromagnetic water meter
The electromagnetic water meter uses the Faraday electromagnetic induction principle to determine the flow rate of the measured medium by measuring the intensity of the induced electromotive force generated by cutting the magnetic induction line generated by the constant magnetic field when the water flows through the measuring tube, and then obtain the flow value.
