The coaxial cable has a heavy-duty jacket with permanent markings precisely laser etched on the cable every 1/100 ft. or each millimeter. The cable reels smoothly, remains flexible, and hangs straight in the well. It comes in lengths from 100 ft. - 1000 ft. (30 m - 300 m).
A braided copper outer conductor gives flexibility and a stranded stainless steel central conductor gives strength. It is easy to repair and splice. The cable jacket is of heavy-duty polyethylene for durability.
The Model 102 Water Level Meter uses a choice of two small diameter probe designs, attached to a narrow coaxial cable, fitted on a sturdy ergonomically designed reel. A standard 9 volt battery, housed in an easy-access battery drawer, powers the Water Level Meter.
When the probe enters water the electrical circuit is completed, sending a signal back to the reel where a light and clearly audible buzzer are activated. The water level is then determined by taking a reading directly from the cable at the top of the well casing or borehole.
A sensitivity control allows the buzzer to be scaled back or turned off while in cascading water, and ensures a clear signal in both high and low conductivity conditions.
Model 102 Probes are designed with segmented weights for flexibility. The probe tip uses a recessed design to minimize false signals in cascading water.
