Sonar water level meter is best used to measure water levels in piezometers, monitoring wells, and bore holes. Designed to be very accurate to great distances, they can also be used to determine total well depth before or after installation. Most of these well tapes, tag lines and cabled meters have probes that detect the water via fluid conductivity. These meters then emit an audio or visual signal to denote where the water level is. This category also includes well sounders, which offer a non-contact depth measurement. Some well tapes even measure the conductivity level and temperature in addition to water level.
