YF-B5 G3/4 1-30L/min Copper Hall-Effect Water Flow Sensor for Water Heaters Agricultural Irrigation

YF-B5 G3/4 1-30L/min Copper Hall-Effect Water Flow Sensor for Water Heaters Agricultural Irrigation

Features:
Water flow sensor
* Imported Hall effect components
* Quick response
* Wide applications

Fine workmanship and high-quality materials
* Sealed and watertight
* Wear-resistant
* Comply with ROHS testing
* High sensitivity

The raw materials comply with RoHS standards
* The water flow sensor is mainly composed of a copper valve body, a water flow rotor assembly, and a Hall sensor. It is installed at the inlet of the water heater and is used to detect the incoming water flow rate. When water passes through the rotor assembly, the magnetic rotor rotates, and its speed changes according to the flow rate. The Hall sensor outputs corresponding pulse signals, which are fed back to the controller. The controller then determines the water flow rate and performs necessary adjustments.

Application range
* Suitable for water heaters, water dispensers, water vending machines, and campus card machines.

Instructions for Use:
1. To prevent particles and debris from entering the sensor, a filter must be installed at the water inlet of the sensor.
2. The water flow sensor should be installed indoors or within the equipment. It should not be exposed to outdoor or harsh environments with high humidity or temperature for extended periods. The sensor installation should avoid vibration and shaking environments to prevent affecting the measurement accuracy.
3. The characteristics of the sensor may change when magnetic materials or materials generating magnetic force come close to the sensor.
4. Do not disassemble the water flow sensor to prevent damage. Any water flow sensor that has been disassembled is not covered by the warranty.
5. If this type of sensor has not been used before, there may be issues when directly replacing it. Please raise any concerns promptly.
