Water Flow Sensor

Water flow is measured by a turbine flow sensor that is fed by a DC signal of 5 V, and
gives a proportional feedback to the measured water flow.
- Flow rate to operate the appliance: 2.8 l/min
- Flow rate to shut off the appliance: 2.4 l/min
Water flow characteristic curve formula： f = 6.9 x Q
Note:
f is output frequency (Hz)
Q is water flow rate (L/min)
In case Q > 2.8l/min following P
- If P > Minimum Power, the appliance will run with the calculated minimum water
