i am not getting any output i tried calibrating and it does not work, the pump is moving water but there is no reading being displayed
Well, I just calibrated 2 of these yesterday and I had no issues doing that ... !
That being said make sure to go by the book (manual) and ensure that prior to calibration your system meets
the requirements to calibrate itself like having the pump work on more than 3000 rpm, have more than 80L per minute or hour
(i can't recall because using gallons is more convenient for me), use their liquid or (in my case) pure distilled water and block the
flow after starting the calibration for nearly 30 secs ... (it is a give or take 3 step calibration).
Using other liquids can affect the calibration and it makes sense as long as we are talking about an algorithm and not an actual
flow sensor here which means that the algorithm variables must be met in order for it to provide to you an output (flow estimation
)
I hope that helps !
