Solinst Water Level Meters Model 101

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.

• Markings each 1/100 ft. or millimeter

• Sensitivity adjustable to conductivity
• Shielded probes to avoid false readings

• Permanent, heat impregnated markings
• Non-stretch stainless steel conductors
