1.2inch DN32 DC4.5 5V-24V 2～120 L/min Water Flow Sensor

1.2 inch DN32 DC4.5 5V-24V 2 ~ 120 L / min water flow sensor
Features:
1, the product looks lightweight and flexible, small size, easy installation.
2, impeller inlaid stainless steel beads, never wear.
3, the seal structure of the force will not leak.
4, Hall components imported from Germany, and encapsulated with potting to prevent moisture, never aging.
5, all raw materials are in line with ROHS testing standards
First, the introduction:
Water flow sensor from the plastic body, rotor assembly flow and Hall sensor. It is installed at the inlet of the water heater to detect the water flow when the water flows through the rotor assembly and the speed of a magnetic rotor changes with the flow rate. The Hall sensor outputs a corresponding pulse signal and feeds it back to the controller. The controller determines the amount of water Adjust the size.
Be careful:
Non-violent shocks and chemical attacks.
Do not throw or crash.
Vertical installation angle does not exceed 5 degrees.
Medium temperature should not exceed 120 ℃.
Second, the output waveform: square wave
Third, the conduction mode:
IN 1 red is positive
2 yellow OUT signal output line
3 black GND negative
4 green temperature sensor
