YF-B5 Turbine Water Flow Sensor

Features:The hall effect water flow sensor is light, nimble outline, small size and easy to install. All materials are in line with SGS testing standards. 
There is an integrated hall effect sensor that outputs an electrical pulse with every revolution. The hall effect sensor is sealed from the water pipe and allows the sensor to stay safe and dry. 
Stable, high temperature, low water pressure start. 
Three wire connection: Red for positive, black for negative, yellow for pulse signal.

Application:

Water heater, washing machine, boiler, electromagnetic water heater, water dispenser, water purifier, R.O. machine, U.F. machine, coffee machine, water machine, water machine control, water control machine, beer machine, beauty equipment, shower equipment, electrolytic water machine, energy engineering, heat pump,IC meter, steam equipment, irrigation equipment, water system, campus card self-service sale (sell) water machine, washing machine, automatic washing equipment, water treatment equipment, water dispensing equipment, cooling system, circulation system, intelligent toilet (toilet), bidet, mechanical equipment, heating equipment,  Pharmaceutical (agents) equipment etc.

Calculation Formula: 

*F(Hz)= 8*flow rate(Q)(l/min)

*1L=477Hz,

*Error:±5% for both formula;

Note:
1. When magnetic material is close with the sensor, its characteristics may vary.
2. In order to avoid particle debris, the sensor must be installed after a filter.
3. The flow sensor can be installed in any direction. IT has to avoid strong vibrating and shaking environment, so as not to affect the accuracy.
