I have been using flow sensor to calculate the amount of water dispensed . But when water level is less in water tank i.e. flow rate is low the sensor does not works properly. It cannot measure the dispensed amount of water. Is it a known issue with flow sensor is there any overcome of this issue?
Further more its just the reverse when water comes out with good pressure. I was expecting a liter of water to be dispensed - but it dispensed 600 ml of water only. The manual stated 450 pulses for 1 liter of water which actually dispensed qty did not match? I am sure that I am counting each pulse in my code and close valve when I get 450-470 pulses
