Water flow sensor/4 points G1/2 interface water heater water heater water sales water dispenser Hall flowmeter

Features:

1. The appearance of this product is light and light, with a small volume, which is easy to install.

2. The leaf wheels are inlaid with stainless steel beads, which is always wear -resistant.

3. The sealing ring is adopted.

4. The Hall component is imported, and the waterproof glue silicone is used to strengthen the water from water.

5. All raw materials meet the ROHS detection standard

6. Standard G1/2 snail interface installation is simpler and firm.

1. Product introduction:

The water flow sensor is mainly composed of plastic valve body, water flow rotor component and Hall sensor.

It is installed at the water inlet end of the water heater to detect water inlet flow. When the water passes through the water flow rotor component,

Magnetic rotor rotates and the speed changes with the flow of flow, Hall sensor outputs the corresponding pulse

Signals, feedback to the controller, the controller judges the size of the water flow and regulates.

Precautions:

It is strictly forbidden to strictly impact and erosion of chemicals.
It is strictly forbidden to throw or collide.
The medium temperature should not exceed 120 degrees
Third, the line method:

1 Red IN connecting positive pole

2 yellow out signal output cable

3 Black GND is overlapped

4 Green R temperature induction (3950K 50K or 3950K 15K please choose to choose according to your requirements)

Frequency: f = 7.5*q (l/min) error: ± 2%

Based on the flow rate of 1L/min, 7.5 * 1 * 60 is equal to the pulse voltage that flows over 1 liter of water output: 3.5-24VDC, the current cannot exceed 10mA, and the output of 450 pulses will be output after a liter water output.

That is, frequency calculation = constant 7.5 * unit flow (L/min) * time (second)

Flow range: 1-30L/min

Fourth, technical parameters

Scope of application:

Suitable for water heater, credit card machine, automatic water sales machine, and other traffic metering equipment!
