Thanks,For the application I'm considering, the flow sensor will be mostly horizontal. I'll try necking down the flow and see if it helps. I have not been able to find any low-flow sensors that are priced reasonable.
Did you ever find anything that would work for a "low flow" on and off type system without breaking the bank? If so, could you share what you found? if not, what did you do to make it work?
thanks,
Andy
