102 Laser Marked Water Level Meter

Water level meter with a narrow laser-marked coaxial cable and a choice of two small diameter probes.

P4 probe (4 mm) for very narrow diameters, or P10 probe (10 mm) with flexible segmented weights
Polyurethane-jacketed cable laser marked every millimetre or 1/100 ft, in lengths from 30 m to 300 m (100 ft to 1000 ft)
Light and audible buzzer with an adjustable sensitivity control

Overview

The Solinst Model 102 Laser Marked Water Level Meter is designed to measure groundwater levels, especially in small diameter tubes and piezometers, or where a flexible assembly is needed to get past down hole instrumentation. It uses a choice of two small diameter probes attached to a narrow coaxial cable, fitted on a sturdy reel and powered by a standard 9 volt battery. When the probe enters water, a light and buzzer activate, and the water level is read directly from the cable at the top of the well casing or borehole.

Typical applications

Measuring groundwater levels in small diameter tubes and piezometers
Water level measurement where a flexible assembly is needed to get past down hole instrumentation
Water level measurement in monitoring wells (P10 probe)
Shallow applications and very narrow diameters, including the channels of the Solinst CMT System, Drive-Point Piezometers and narrow open tubes (P4 probe)

Key Features

Choice of two narrow stainless steel probes: P4 (4 mm) or P10 (10 mm)
P10 probe with 10 stainless steel weights in a flexible assembly that allows easy well access and keeps the cable hanging straight
Recessed probe tips minimize false signals in cascading water
Coaxial cable with a durable polyurethane jacket and permanent laser markings every millimetre or 1/100 ft
Braided copper outer conductor for flexibility and stranded stainless steel central conductor for strength
Cable is easy to repair and splice
Sensitivity control allows the buzzer to be scaled back or turned off in cascading water and ensures a clear signal in high and low conductivity conditions
Standard reel with battery drawer, brake, carrying handle, battery test button and tape guide
Replacement probes, cables and parts available

Benefits

Narrow: The 4 mm (0.157") diameter P4 probe reaches very narrow tubes and channels.
Long Life: Rugged, corrosion resistant components and a strong, flexible cable that is easily spliced.
Accurate: Precise markings every mm or 1/100 ft, traceable to national standards.
