This Water Level Meter mini, featuring a compact stainless-steel probe of just 14 mm diameter, is standard equipment for measuring groundwater levels. The probe is mounted on a tape graduated in centimetres. When the probe contacts conductive liquid, it emits a clear acoustic and light signal. Slightly lifting the cable stops the signal, and the depth can then be read directly from the tape. The instrument’s accuracy is approximately one centimetre.
The start/stop method used during preliminary pumping is designed to limit water level drop, thereby reducing the risk of soil particles being drawn into the filter pipe and improving the accuracy of analyses. This meter is compatible with the Royal Eijkelkamp peristaltic pump.
