Calibrate by counting the number of pulses while filling a 20L bucket. The 'mites can handle the pulses with their eyes closed. When watering, I pump 10,000L/day+ from the bore into a tank and from the tank to the gardens. 900L is a doddle.   Quote   How do you determine and record the start time of the flow? If you are stand alone, I would get an RTC. Then just read every 30 seconds and log any period that has a difference in pulse count. You could easily go to 10 or 15 seconds for a quicker response. Jim
