It might be the accuracy, although I haven't run into this situation.
I have the Microstream sensor, which works a bit better than the Futurelec one and I will try the new Bio-tech with the larger nozzle diameter.
I flashed the calibration script back to the unit to watch it counting. You can see the counts stop below about 1700 rpm.
This sensor is a turbine type flowmeter. Have you ever seen a positive displacement type flow meter for gasoline? I have used them for water meters in the past.
I guess the lager nozzle size would make it less accurate at low flow rates?
Have you got some web links to the other sensors?
