Product Description

FS300A water flow sensor g3/4 high precision flow meter automatic selling water meter

Product features:

1. This product is light and convenient in appearance, small in size and easy to install.

2, the inner set with stainless steel bead shaft, impeller from the traditional rotation around the point to extend the life of the face.

3, porous shunt water small flow does not leak, and keep the blade constant rotation, sealing ring with the upper and lower force structure never leak.

4. Hall components are imported, isolated and waterproof.

5. All raw materials meet ROHS testing standards.

Product profile:

The water flow sensor is mainly composed of plastic valve body, water flow rotor assembly and hall sensor.It is installed at the water inlet end of the water heater and is used to measure the inflow rate as water passes through the flow rotor assembly.

The magnetic rotor rotates and the rotation speed changes with the flow rate.

The hall sensor outputs the corresponding pulseThe signal is fed back to the controller, which judges the size of water flow and regulates it.

Precautions for use:

Severe shock and chemical erosion are strictly prohibited.

Throwing or bumping is strictly prohibited.

Medium temperature should not exceed 100 degrees.

Output waveform: square wave

Outgoing line:

1 red IN to the positive pole

2. Yellow OUT signal output line

3 black GND with negative electrode

Frequency: F=5.5*Q(L/Min) error: ±2%That is, frequency calculation = constant 5.5* unit flow (L/min) * time (s) flow range: 1-60l /min
