Product overview:

This product is mainly composed of copper valve body, solenoid valve, water flow rotor assembly and Hall sensor. The computer is installed on the waterway system to detect the flow of water. When the front end solenoid valve is powered on. The valve is open. When water passes through the water flow rotor assembly, the impeller drives the magnetic ring to rotate. The speed of the impeller changes with the flow rate. The Hall sensor outputs the corresponding pulse signal, which is fed back to the controller. The controller calculates the water flow according to the number of pulses. The advantage of this product is that it avoids the problem of water seepage at the connection between the flowmeter and the solenoid valve, and improves the consistency and accuracy of the product. This product can be divided into pressurized water supply and non pressurized water supply. Customers can choose the water supply mode according to their needs.

Precautions: During installation, the direction indicated by the arrow shall be consistent with the water flow direction; During installation, the pipeline shall be kept horizontal and the gradient shall not exceed 5 degrees; It is strictly prohibited to have severe impact and chemical substances; Throwing or collision is strictly prohibited; The medium temperature should not exceed 100 ℃; Avoid ferromagnetic objects and equipment with strong electromagnetic field as far as possible, so as not to affect the working magnetic field and flow signal of the sensor; There shall be sufficient space around the flowmeter for installation and maintenance.
