Water level meter 101


For measuring the depth of water in wells, boreholes, and standpipes, the Model 101 Water Level Meter is the most accurate and reliable meter. It is sturdy, easy-to-repair and read to 1/100 ft. or to each millimeter.

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.
