Solinst 101 Water Level Meter The Solinst Model 101 P2 Water Level Meter with embossed tape offers the accuracy and reliability you expect from Solinst. The 101 P2 Water Level Meter uses non-stretch polyethylene flat tape, with heat embossed markings each 1/100 ft. or mm. Designed for measuring accurate water levels in wells, boreholes and standpipes, the rugged free-standing reel is well balanced and ideal for use in the field. The 101 P2 Water Level Meter Probe is very easy to repair. Available in flat tape lengths to 6000 ft. (or 1800 m). Also available, from Solinst, are the less expensive laser marked Model 102 Coaxial Cable Water Level Meter for use in small diameter tubes, and the 102M Mini laser marked Water Level Meter in lengths of 80 ft. and 25 m.

Operating Principles

The Model 101 Water Level Meter uses a choice of probe designs, attached to a permanently marked polyethylene tape, fitted on a well-balanced reel. It is powered by a standard 9 volt battery housed in an easy-access battery drawer. The conductors embedded within the tape, each have seven strands of stainless steel for strength and flexibility.
The probe incorporates 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.

 

Tape Specifications

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.
