_______________Product Information______________
Feature:
1. USE PRINCIPLE: When the water passes through, the magnetic rotor rotates and the speed changes, the sensor outputs the corresponding pulse signal and feeds it back to the controller to judge the water flow.
2. SENSOR
Specification:
The turbine water flow sensor has 3in male thread interface, the working voltage range is DC5-18V, and the output NPN pulse signal.
3. EASY INSTALLATION: The water flow sensor is light in weight and small in size, with standard size and good sealing, easy to install and does not take up space.
4. GOOD PERFORMANCE: The water flowmeter sensor is stable in operation, resistant to high temperature, and can be started at low water pressure, with strong practicability.
5. MULTIPLE USAGES: Can be used in water heaters, credit card machines, water vending machines, flow measurement equipment, etc., with a wide range of applications.
