I would like to measure the height of a sump which varies by about 7m vertical through a relatively straight but small passage of length 30-40m. I would like to record the data for up to about a month at a time, and in intervals of about 1 hour (750 readings max).
Has anybody got any bright ideas, methods you have used in the past for this sort of thing, or just knowledge of what doesn't work?!?
Cheers.
