The Solinst 101 Water Level Meter is ideal for water level measurement in boreholes, standpipes and wells. It is the most accurate and reliable Water Level Dip Meter in the Solinst Range. This water level meter is very easy to operate and read to each millimetre or 1/100ft.

Choices of probe designs are available on these water level meters.

On the P7 version each probe is attached permanently to laser marked PVDF flat tape which is fitted on a well balanced reel. This water level meter has a PVDF flat tape and has increased tensile strength and improved electrical efficiency by using 6 strands of copper coated stainless steel and 13 strands of stainless steel in each conductor. The P7 pressure probe is submersible to 300 m (1000 ft) and has the sensor mounted at the tip to provide consistent accuracy.

The P2 probe version has a simple design which is easy to clean and hangs straight in wells. The P2 probe is mounted on a heat embossed polyethylene tape which is easy to repair.

A 9 volt battery housed in an easy access battery drawer powers the meter.

Borehole monitoring
Well and level measurement



The high quality polyethylene tape reels smoothly, remains flexible and hangs straight in the well, irrespective of temperature. Permanent markings at each millimeter or 1/100 ft. allow accurate readings, traceable to national standards. The 3/8” (10 mm) wide tapes come in lengths up to 6000 ft. (1800 m).

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. Markings are permanently impregnated onto one side of the tape in your choice of scale.

Probe Options Probes are designed to reduce or eliminate false readings in cascading water.
P2 Standard Stainless steel with a neoprene strain relief. Not suitable for submergence to any significant depth. Easy to repair.
Size: 0.55” dia., 7.5” long (14 mm x 190 mm)
P7 Submersible The P7 Probe is submersible up to 1000 ft. (300 m), ideal for measuring total well depth. The sensor at the tip of the probe provides consistent measurements with almost zero displacement. The tape seal plug design allows the probe to be quickly and easily replaced, if required. Size: 5/8” dia., 5.38” long (16 mm x 137 mm)

The P7 probe is pressure rated and can be entirely submerged up to 300m, so can be used to measure total well depth. The zero point on this probe is very near to the probe tip and therefore has near to zero displacement.

Size: 16mm x 137mm

Weight: 128g

The P7 probe connects promptly to the Tape seal plug of the Solinst PVDF Laser Marked flat tape used and, if required, the tape seal plug can be replaced with ease.

The P2 probe is used for tagging the water level and therefore should ideally not be submerged, but has a shielded design to significantly reduce false readings in descending water. The zero point is near the middle of the probe so more displacement may occur.

Size: 14mmx190mm

Weight: 200

The P2 probe is permanently installed onto the heat embossed high quality polyethylene tape.

Both use a flat tape which come with markings every millimetre or 1/1000 ft and have a thick dog-bone design to deter from attachment to wet surfaces.
