    Although all of our water level gauges can be used for well measurement, these well depth gauges are specially designed for this purpose. Gauge and air line in the well are charged with air. The pressure required to permit air to escape from the end of the air line is equivalent to the head of water above the air line. Gauge measurements are in 1 ft H2O graduations.

    Set length of air line on the adjustable dial to permit reading water levels below ground surface. Levels range from 0 to 393 ft or 330 to 600 ft, depending on the model. Do not subject the gauge to pressures over 90 psi (or 207 ft head), regardless of tubing length.

    Note: Order the optional bicycle-type air fill valve for field gauge line pressurization.
