Model 300 Sonic Water Level Meter
This self-contained, battery operated meter uses sound waves to measure well water level. Fast, accurate measurements are possible in the field or anywhere, without the use of down-hole instrumentation. Lightweight, compact, versatile, and easy to operate, the water level meter allows you to measure crooked wells, wells with cascading water, partially cased rock wells, wells with submersible pumps, capped or uncapped wells, wells with pipes and wires inside, plus you can even measure the length of coiled pipe. As long as the obstructions take up no more than half of the bore area, the meter will not suffer any loss of accuracy. The sonic water level meter should only be used on wells under 10 inches in diameter as the accuracy decreases with larger diameter wells.
