Laser Marked Water Level Meter Model 102
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.
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 scaled back or turned off while in cascading water, and ensures a clear signal in both high and low conductivity conditions.
Probes
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.
Laser Marked Cable
The coaxial cable has a durable polyethylene jacket with permanent markings precisely laser etched on the cable every
1/100 ft. or each millimeter.
The cable reels smoothly, remains flexible, and comes in lengths from 100 ft. – 1000 ft. (30 m – 300 m).
