Solinst Model 101 P2 Water Level Meter
Solinst Water Level Meter Model 101 w/ P2 Probe
For measuring the depth to water in wells, boreholes, standpipes, and tanks, Model 101 P2 Water Level Meters are the industry standard for portable hand operated meters. They are sturdy, easy to use and read accurately to 1/100 ft. or each millimeter.
Operating Principles of Solinst Model 101 P2 Water Level Meter
Model 101 Water Level Meters use corrosion proof stainless steel probes attached to permanently marked flat tape, fitted on a well-balanced reel. They are powered by a standard 9 volt battery. The probes incorporate an insulating gap between electrodes. When contact is made with water, the circuit is completed, activating a loud buzzer and a light. The water level is then determined by taking a reading directly from the tape at the top of the well casing or borehole. A sensitivity control allows the buzzer to be turned off while in cascading water, and ensures a clear signal in both high and low conductivity conditions.
With a stand-alone design, convenient carrying handle, and sturdy probe holder, the standard reels are ergonomically designed for ease of use. They are robust and smooth running. The battery is housed in a convenient drawer in the front of the reel, allowing quick replacement. The reels are equipped with an on/off sensitivity switch, light, buzzer, battery test button, brake and a tape guide stored on the frame.
The P2 Probe is shielded in design to reduce or eliminate false readings in cascading water. The probe consists of a stainless steel body with a neoprene heat shrink seal. It is not suitable for submergence to any significant depth. Its simple design makes it easy to repair.
Size: 0.55" dia., 7.5" long (14 mm x 190 mm)
Weight: ~7 ounces (200 g)
The Model 101 P2 Water Level Meter uses high quality polyethylene tape that reels smoothly, remains flexible and hangs straight in the well. Heat embossed marking each millimeter or 1/100 ft. allow accurate readings. The 3/8" (10 mm) wide tapes come in lengths up to 1000 ft. (300 m). 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. M2 Feet and tenths: with markings every 1/100 ft. M3 Meters and centimeters: with markings every mm.

Solinst Model 101 P2 Water Level Meters are available on reels as shown below, in the following standard lengths:
Small Reel * 100 ft. 30 m * 200 ft. 60 m * 300 ft. 100 m
Medium Reel * 500 ft. 150 m * 750 ft. 250 m * 1000 ft. 300 m
Carrying Case: Small and medium padded nylon carrying cases are available, as an optional extra. Their design has a convenient shoulder strap, zippered front pocket, zippered top, and a grommet in the base to prevent moisture build-up.
Tape Guide/Datum A tape guide is provided with each Meter. It protects the tape from damage on rough edges of well casing and ensures easy, consistent measurements, regardless of who takes the readings. It can also provide support on the casing, for small reels.
Power Reels: Power reels can be very useful to allow faster or less strenuous operation of longer lengths of tape.
