Has anyone tinkered with real-time measurement of very light vacuum?
It happens that the suction level in my basement radon abatement system is a leading indicator of basement water infiltration. When the water table rises, the suction in the radon pipe increases. A rising suction level means I ought to take precautions, test the pumps, etc., and the earlier I know, the better. Having a trend line and/or a threshold trigger would be the objective.
The suction level in this system is very very low, from 0.5 to around 2.0 "inches of water," the entire range of which is about 0.1 PSI, minuscule relative to atmospheric pressure. If anyone has dealt with this challenge, I'd appreciate knowing your experiences.
Edit: Forgot to say that I can read the pressure manually with a venturi-type sight glass on the side of the pipe column.

[ If you are not familiar with this kind of basement radon abatement installation: A 4-inch plastic pipe runs tight into a hole in the basement slab. The other end of this pipe is outdoors, having an enclosed fan unit that pulls air from under the slab, which has the concentration of radon gas from the earth, and exhausts the gas safely into the air. Otherwise the radon gas would seep into the basement and from there concentrate in the house. This is a common problem in New England. ]
