the permeable membrane, that the pressure difference across a
practical membrane determines not only the rate of flow of the
desired material, but also the leakage of the undesired.

I suspect that this is due to some molecules such as H2O would only
get "stuck" in the membrane if it's able to discriminate between the
"diameter" of O and N in their respective gases. When sufficient
pressure is applied, the weak repulsive forces between molecules of
the gas and membrane can be overcome to some degree and the
effective diameter reduces.

better, a cheapie
pwm radio/control type as someone else mentioned is ideal. However, some
years ago
I had to recalibrate the speedo on a vl calais turbo and found I could
move the
rotating magnet assembly further or closer to the reluctance wheel, so if
you have any pickup at all anywhere on the rear - or even front then you can
try this trick instead,
