Model 102 Narrow Diameter Cable Water Level Meters

solinst model 102 water level indicators


The Model 102 Water Level Meters use narrow diameter cable to measure water levels in tight spaces. The segmented P10 Probe offers greater flexibility in angled piezometers and assist in bypassing down-hole restrictions or pumps when measuring draw-down.

The Model 102 Water Level Meters use the same reliable electronics and reel as the Model 101 Water Level Meters; the use of accurately marked coaxial cable makes it a more affordable option.

The cable has a tough polyethylene jacket with laser markings each 1/100 ft. or millimeter. The braided copper outer conductor provides flexibility, while the stainless steel central conductor reduces stretch and resists corrosion. The cable is easy to repair and splice.

There are two narrow probe options to choose from. Their probe tip designs minimize false signals in cascading water.

Helpful for reaching greater depths, the heavier 3/8" x 2.75" (10 mm x 70 mm) P10 Probe weighs 6.14 oz. (174 g) with 10 segmented stainless steel weights for easy handling.

For the narrowest applications, the 0.157" x 1.5" (4 mm x 38 mm) stainless steel P4 Probe is the choice. It weighs 0.35 oz. (10 g).

The 4 mm P4 stainless steel probe is also ideal for measuring in the narrow channels of a Model 403 CMT® Multilevel System and the 3/8" (10 mm) open tubes of a Model 401 Waterloo Multilevel System.

The Model 102M Mini Water Level Meter comes with either 80 ft. or 25 m of laser-marked coaxial cable on a more compact, portable reel that can fit in a backpack or Solinst mini carry case. The 102M Mini also comes with the choice of a P4 or P10 Probe.
