YF-S201C Flow Turbine Flowmeter Water Flow Sensor Hall Flow (Transparent)

Description

• The water flow sensor is mainly composed of a plastic valve, a water flow rotor assembly and a hall sensor.
• It is equipped with a water inlet at the end of the water heater to detect the water flow rate.
• When water passes through the water flow rotor assembly, the magnetic rotor rotates and its speed changes with the flow rate.
• The hall sensor outputs the corresponding pulse signal and feeds back to the controller.
• Judge the water size and adjust it. Product appearance and convenience, small size, easy installation, and the impeller is embedded with stainless steel beads, which is wearable.
• Circuit and water isolation design, Hall elements are imported, and the valve is made of transparent material to facilitate observation of water and rotor conditions.
• All raw materials are in line with ROHS testing standards.
• Scope of application: suitable for water heaters, credit cards, automatic water vending machines, and other flow measuring devices.
