- LED Light and loud buzzer indicates water level
- Adjust sensitivity to suit your application
- Clearly-marked cable with greater flexibility and abrasion-resistance
The Laser Marked Model 102 Water Level Indicator is designed to accurately measure groundwater levels in small diameter applications.
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.

Laser Marked Cable
Laser Marked Flat Tape
The coaxial cable has a durable polyurethane jacket with permanent markings precisely laser etched on the cable every each millimeter or every 1/100 ft.
The cable reels smoothly, remains flexible, and comes in lengths from 30 m – 300 m (100 ft – 1000 ft).
A braided copper outer conductor gives flexibility and a stranded stainless steel central conductor gives strength. It is easy to repair and splice.
Laser Markings Each Millimeter or Each 1/100 ft

Reels and Length Options
Water Level Meter Reels
The standard reel has an easy access battery drawer, a well designed brake assembly, and convenient carrying handle. It has been ergonomically designed to be comfortable in use and stable when placed on the ground. It has an on/off sensitivity switch, light, buzzer, battery test button, and comes with a tape guide.
The mini reel is sturdy, yet very compact and easy to carry. It also has an on/off sensitivity switch, light, buzzer, and battery test button.

Probe Options
Narrow Diameter Probes
Model 102 Water Level Indicator Probes are designed for flexibility. The probe tips use a recessed design to minimize false signals in cascading water.
P10
10 mm dia. x 70 mm long (3/8" x 2.75") stainless steel with 10 stainless steel weights, weighing 174 g (6.14 oz). This probe is ideal for the majority of water level measurement applications. The flexible weight assembly allows easy well access and keeps the cable hanging straight in monitoring wells.
P4
4 mm dia. x 38 mm long (0.157" x 1.5") stainless steel weighing 10 g (0.35 oz), with no weights. It is ideal for shallow applications and for accessing very narrow diameters, especially the channels of the Solinst CMT System, DrivePoint Piezometers or narrow open tubes.
102M Mini Water Level Meter
The laser marked coaxial cable is mounted on a convenient small reel that is light-weight and fits easily into a mini carrying case or backpack. The accurate cable is marked each millimeter or every 1/100 ft.
The 102M Mini Water Level Meter is available in 25 m and 80 ft lengths. There is the choice of the P4 or P10 Probe.
