I believe that a short time ago there was a discussion about this. but
depending on the head of the tank one could use an MPX5000 series
pressure sensor with a dip tube or am I too late?

I have a number of 55 gal drums of water that I would like to know
the depth of in my rain water gathering system so that I don't pump it
dry and ruin a sprinkler pump. I am going to use one of them per drum to
monitor the levels. I believe that the pressure of one foot of head is
.43 PSI and that a drum is about 3 feet deep, giving a pressure of 1.29
PSI. Does this sound correct?



Wouldn't a sensor to determine when the pump loses prime be simpler?


Then I'd have to re-prime the pump. I would like to also be able to
determine the amount remaining in the system if it isn't all pumped in the
time allotted.
