It is difficult to do it without a compressor. May be empty a jet into a sode bottle after one minute of boost (careful, not many roads and sustain one minuter of full boost).

Calibrate the flow sensor with a normal flow. Jeff told me you have problem with the logged sensor signal. If the BMS logger is not reliable, read the floe signal with a voltmeter. You only need to make a quick note of the voltage at full boost. Once done, repeat it on a bench with water from a tap and match the same voltage for one minute. see how much water is collected.
I can use the retained boost in the tank to check flow. The BMS logger is fine. I think I am getting interference from the car. I suspect the flow readings to be approximately correct though. Will look into it.
