Solinst 102 Water Level Meter

Solinst 102 Water Level Meter

The Coaxial Cable Water Level Meter

The Solinst Model 102 Water Level Meter is designed to measure groundwater levels, especially in small diameter tubes and piezometers or where a flexible cable is needed to snake past an in-well pump. The cable has a heavy-duty jacket and stainless steel coaxial conductors for strength. Permanent markings are precisely laser etched on the cable every 1/100 ft. or each millimeter.

Operating Principles

The Model 102 Water Level Meter uses a choice of two small diameter probe designs, attached to a narrow coaxial cable, fitted on a sturdy ergonomically designed reel. A standard 9 volt battery, housed in an easy-access battery drawer, powers the Water Level Meter.

When the probe enters water the electrical circuit is completed, sending a signal back to the reel where a light and clearly audible buzzer are activated. The water level is then determined by taking a reading directly from the cable 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.

Features

  • Narrow - 1/4" (6 mm) probe excellent for use in 3/8" ID (10 mm) flexible tubing
  • Low Cost - Solinst quality at a low price
  • Long Life - Rugged, corrosion proof components, Strong, flexible cable, is easily spliced, Replacement probes, cables and parts
  • Accurate- Markings precisely every 1/100 ft. or mm, Traceable to national standards

Laser Marked Cable

The coaxial cable has laser etched markings every 1/100 ft. or each millimeter, to provide high accuracy and reliability. The cable reels smoothly, remains flexible, and hangs straight in the well. It comes in lengths from 100 ft. - 1000 ft. (30 m - 300 m). A tinned copper-braided shield gives flexibility and a stranded stainless steel central conductor gives strength. It is easy to repair and splice. The cable jacket is of heavy-duty polyethylene for durability.

Probes

Model 102 Probes are designed with segmented weights for flexibility. The TeflonŽ tip uses a recessed design to minimize false signals in cascading water.

P1
1/4" dia. x 1.5" long (6.4 mm x 38 mm) stainless steel with 12 weights, weighing 2.5 oz (70 g). It is ideal for accessing narrow diameters.

P2
3/8" dia. x 1.5" long (10 mm x 38 mm) brass with 10 weights, weighing 4.6 oz (130 g). The heavier probe is ideal for greater depths.
