I'm trying to measure and regulate gauge pressure in a pipe that has water flowing through it, but I need the pressure to be about .75psi (1.8 ft H2O). Most dial gauge ranges are too high and not accurate enough. Pressure transducers Ive had no luck with as far as finding one thats inexpensive and measures accurately under 1 psi for water. Using a liquid column would be too high for water (2 ft). So any ideas, products or guidance? I have no problems using an analog transducer that outputs voltage if that's a good option.
