I tried different debounce time. I found that the best one depends on the rate of flow of the water.
For exemple at constant high rate of flow, 1 second debounce time give exactly the same amount of liter than the water meter.
But if I reduce the rate of flow, the number of liter increases abnormally.

I use 100 mSec for debounce time. Could you try it too?

Dit it. No good as soon as it starts, it measures 5 liters (10/2) instead of 7.

This sensor is not like a switch, but gives a proper square wave signal.
It probably uses a Hall sensor and a magnet.

This means the debounce should not be needed at all.
It could be there is some issue with the plugin, I haven't looked at its implementation yet, on how it is using this debounce feature.

Edit:
I was just thinking about these sensors. Is it possible the flow sensor is acting a bit strange when starting/stopping the flow?
For example rotating back/forward when starting/stopping, or at a low flow rate?

Thank you for your help.
It was not designed to be a switch, but using the switch setting with ESPeasy gives very good result.

I don't think it's a all sensor, I have joined the picture of the sensor, it seems to be an ILS switch.

If the sensor goes backwards, I see it on the mechanical meter and this is not the case.
The flow is of course not constant, but for sure nothing seems abnormal.
