Solinst 101B Water Level Meters

The Model 101B P1 Probe is made from durable stainless steel. It is designed to reduce false signals in cascading water, and is leak-proof.

Low cost, simple and long life

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.

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.

Heat Embossed Polyethylene Flat Tape

The Model 101B Water Level Meter uses high quality polyethylene flat tape with accurate heat embossed markings every centimeter and meter.

The 10 mm (3/8") wide tape reels smoothly, remains flexible, hangs straight in the well and is available in 30 m, 60 m, and 100 m lengths.

Seven stranded stainless steel conductors resist corrosion, provide strength and are non-stretch. The tape is very easy to repair and splice. The dog-bone design reduces adherence to wet surfaces.
