MJ-HZ21CB Brass Integrated water flow rate sensor

Water flow sensor consists of a plastic valve body, a water rotor, and a hall-effect sensor.
When water flows through the rotor, rotor rolls. Its speed changes with different rate of flow. The hall-effect sensor outputs the corresponding pulse signal.

Remark：

Don't disassemble when the product is found to have quality problems .
For dry air sensor within the residual water should pay attention to the blowing pressure <0.3MPa and intermittent output impeller.Can not be rotated at high speed in the anhydrous state .


Connection mode:

RED line for power+
BLACK line for power-
YELLOW line for signal output

Products are packed in cartons, using foam shock absorption and compression to prevent damage in transit.
Also can adjusted by your request.
