Product Overview


Taidacent G1/2 DN15 Plastic Flow Sensor Transparent Liquid Turbine Flow Meter Precision Hall Sensor Water Flow Sensor Switch
Product Description
Water flow sensor is mainly composed of plastic valve body, water flow rotor assembly and Hall sensor. It is installed at the inlet end of the water heater and used to detect the inlet water flow. When the water passes through the water flow rotor assembly, the magnetic rotor rotates and the speed changes with the flow rate change. The Hall sensor outputs the corresponding pulse signal and feeds it back to the controller, which is controlled by the The device determines the size of the water flow and regulates it.
Frequency: F = 5 * Q (L / Min) -3 Error: ± 2% Voltage: 3.5-24VDC, current cannot exceed 10mA, output 300 pulses after one liter of water
That is, frequency calculation = constant 5 * unit flow rate (L / min) * time (seconds)-3 (correction value-can be reduced or not)
Flow range: 1-30L / min
Minimum rated working voltage: DC4.5
Maximum working current: 15mA (DC5V)
Working voltage range: DC3.5-12V (24V can be customized)
Load capacity: ≤10mA (DC5V)
Operating temperature range: ≤80 ℃
Operating humidity range: 35% ~ 90% RH (no frosting)
Allowable pressure: water pressure below 1.75Mpa
Storage temperature: -25 ~ + 80 ℃
Storage humidity: 25% ~ 95% RH
suitable for water heaters, credit card machines, automatic vending machines, and other flow measurement equipment!
1.The appearance of this product is light and flexible, small in size, easy to install.
2.The inside of the impeller is set with stainless steel beads, which is always wear-resistant.
3. Line and water isolation design.
4. The Hall element is imported, and the valve body is made of transparent material to facilitate better observation of water flow and rotor conditions.
5. All raw materials comply with ROHS testing standards
Leading way:
