Operation of Water Level Indicator
|
Applications The water level indicator is used to measure water levels in standpipes and wells. Operation The indicator consists of a probe, a cable with laser-marked graduations, and a cable reel. The hub of the cable reel contains batteries, electronics, a bright LED lamp, and a beeper. The operator lowers the probe into the standpipe or well. When the probe contacts the surface of the water, the LED illuminates and the beeper sounds. The operator then reads the depth-to-water measurement from graduations on the cable. |
