I just added a water meter to my flukso on port 3 as a pulse input. The meter gives a pulse from a reed relay at 1 pulse equals 10 litres, so I set the constant to 10.
The graph on the flukso dash looks ok but when the water stops flowing the graph line does not go to zero it just sits at its last pulse reading. I guess water works differently to other sampling as a valve can fully close very quickly taking you from max flow to no flow so there is no gradual change in pulses to get you down to zero as there is with power for example.
Do i need to look at a pull up/down resistor to zero the reading or do I need to drive a schmitt trigger with the reed relay pulse to produce something more akin to an S0 pulse output whcih the flukso seems to have no trouble with (like my pulse kwhr meters)?
