3:Installation Instructions

1) its characteristics may change when a magnetic material or to produce magnetic material near the sensor.

2) Enter the sensor in order to avoid particle, sundry, the sensor must be installed filters the water entry.
3) The installation of water flow sensor need to avoid strong vibration and shaking environment, so as not to affect measuring accuracy of the sensor.
4)Please do not disassemble without authorization flow sensors in case of damage, water flow sensors to disassemble a are out of place in the warranty scope.
5) Ever and Never used the structured sensor, when used for direct replacement may be not appropriate place, please timely put forward.

4:Connection Mode
RED line for power+
BLACK line for power-
YELLOW line for pulse signal

5:Application

Widely used in water industrial field, thermostatic water heater, boiler, water dispensers, coffee machines, hot card machines, steam equipment, water system, the campus card sales, selling self-help water systems, water treatment equipment, cooling systems, mechanical equipment, instrumentation, pharmaceutical equipment, water purifier and smart card equipment.
