Basic Water Level Meter 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.
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.
Sturdy Reel and Handle The Model 101B Water Level Meter has a sturdy frame
and ergonomic handle for winding the tape. A brake is also
included on the reel.
The faceplate is easy to remove in order to access the 9 volt
battery for replacement. For convenience, there is also a probe
holder on the front of the faceplate.
Robust Accurate Probe
The Model 101B P1 Probe is made from durable stainless
steel. It is designed to reduce false signals in cascading water.
The probe is extremely easy to replace.
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. They make the tape
very easy to repair and splice. The dog-bone design reduces
adherence to wet surfaces.
