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, and make this electronic water meter one of the most trusted on the market.<

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.

Reels and Electronic Controls

Standard reels are ergonomically designed for good balance and ease of use, with a stand-alone design, convenient carrying handle and an excellent brake for stopping the tape from descending. The battery is housed in a convenient battery drawer and each reel has a probe holder and brake. Each reel is equipped with acombination on/off sensitivity switch, light, buzzer, and a battery test button.

Tape Guide

A tape guide is provided on the reel with each standard electronic water level meter. It protects the tape from damage on rough edges of well casing and ensures easy, consistent measurements, regardless of who or where you take your readings.
