This sonic water level meter provides an accurate measurement for the measurement of water level in drilling holes or water level pipe ,particularly suitable for hydropower engineering underground water level or artificially inspection dam observation.
This instrument can be used in construction period, but also can be used as the long term safety monitoring project. This complies with the dam safety monitoring technology standard (SL60-94).

Probe diameter 14mm or 25mm
Our water level meters use corrosion proof stainless steel probes attached to permanently marked flat tape, fitted on a well-balanced reel. They are powered by a standard 9 volt battery.
The probes incorporate an insulating gap between electrodes. When contact is made with water, the circuit is completed, activating a loud buzzer and a light. The water level is then determined by taking a reading directly from the tape at the top of the well casing or borehole.
A sensitivity control allows the buzzer to be turned off while in cascading water, and ensures a clear signal in both high and low conductivity conditions.
