Connected to Arduino and counted pulse. I have no way of knowing how this translates to a stream as the device arrived with no documentation. So it's useless and I'm afraid it was a waste of time and money. If you want to claim that there is or isn't a flow, that's fine. Knowing what the flow is isn't easy to know unless you want to do the calibration yourself.
