Water Level Indicator
The water level indicator is used to measure water levels in standpipes and wells.
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.
About Laser-Marked Graduations
The photograph at right shows a water level indicator cable being drawn through the laser marking machine. The machine directs a laser beam at the cable jacket. The jacket changes color where the beam strikes, and the resulting marks and characters become a permanent part of the cable jacket.
