The Solinst Model 101B Water Level Meter is designed to be an economical and basic, yet durable instrument to measure groundwater levels. It is ideal for measuring depth to water in wells, boreholes, standpipes, and tanks. Also available from Solinst, are the Standard Model 101 Water Level Meters that feature a laser marked PVDF flat tape, and the Model 102 Coaxial Cable Water Level Meters. Both options allow shut-off and sensitivity adjustment (See Model 101 and 102 Data Sheets).

Water Level Meter Operating Principles

The Model 101B Water Level Meter uses a solid stainless steel probe, connected to durable polyethylene flat tape. A standard 9 volt battery, housed inside the reel hub, powers the Water Level Meter. The electronics are coated for water resistance.

When the probe enters water, the electrical circuit is completed, sending a signal back to the reel where a light and clearly audible buzzer are activated. The water level is then determined by taking a reading directly from the tape at the top of the well casing or borehole.

Optional Extras

Also available to purchase are the convenient carry bag and tape guide.
