Jim Amdal explains a method that will allow you to measure—easily and accurately—the amount of water that your big elevated storage tank contains. The project, says Jim, should cost you no more than $10 and two hours.

Determining how much water I had in my water tank used to be a real chore (what with having to climb the tower in order to peer through the tank's manhole) ... until I devised a painless—yet accurate—way to check the container's water level while I stood on the ground.

The answer? A simple sight gauge which uses the compression of air in a length of clear plastic tubing as an indication of water pressure ... which-in turn-is nothing but a reflection of the tank's water capacity.

The accompanying drawings will give you an idea of how the system is set up. As you can see, there's nothing complex about the gauge's construction (I built mine in two hours at a total parts cost of less than ten dollars ... and I'm sure you can do the same). About the only slightly thorny part of the whole project is the calibration of the sight-tube ... and even that's a snap when you know how.

Any ideas for how long the clear tube should be?
