Water Flow Sensor FS300A

JOD15.00
Tax included

Working Flow Rate: 1-60L/min

 

Water flow sensor is mainly composed of plastic valve body, flow of rotor components and hall sensor.
It is installed in the water heater inlet, used to detect water flow, when the water through flow rotor components,
Magnetic rotor rotation and speed changes with the flow, hall sensor output pulse accordingly
Signal feedback to the controller by the controller to judge the size of the water flow, adjust and control.
Use notice:
It is forbidden to severe impact and chemical erosion.
It is forbidden to throw or collision.                          
Vertical installation, to no more than 5 degrees.                        
Medium temperature should not be more than 1200 c.

1 red IN connect the anode
2 yellow OUT signal output line
3 black GND connect the cathode
Frequency: F = 5.5 * Q (L/Min) error: plus or minus 2% voltage: 3.5-24 VDC, current should not exceed 10 ma, 330 pulse output flow through a litre
The frequency calculation = constant flow rate (L/min) 5.5 * unit time (in seconds) flow range: 1-60 L/min

 

Technical parameters
Scope of application:
Apply to the water heater, this device, automatic water machine, such as flow metering equipment.
