Product features:
1, this product appearance is light and agile, small volume, easy to install.
2 internal set with stainless steel shaft, impeller, wear forever.
3, sealing ring, the force of the structure under never leak.
4, hall element, USES the German import and encapsulated with potting glue, prevent water, never aging.
5, all raw materials meet ROHS testing standards
Product synopsis:
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.
Second, the output waveform: square wave
Three, lead way:
1 red IN connect the anode
2 yellow OUT signal output line
3 black GND connect the cathode
4 green R temperature sensor (50 k, 3950 k or 3950 k please customers according to the requirements of their chosen)
YF - S201 frequency: F = 7.5 * Q (L/Min) error: plus or minus 2% voltage: 3.5-24 VDC, current should not exceed 10 ma, 450 pulse output flow through a litre
The frequency calculation = constant flow rate (L/min) 7.5 * unit time (in seconds)
Working range: 0.3-6 L/min
