Laser Marked Water Level Meter Model 102M

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 1/100 ft. or each millimeter. The 102M Mini Water Level Meter is available in 80 ft. and 25 m lengths. There is the choice of the P4 or P10 Probe.

Operating Principles

The Model 102M 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 orturned off while in cascading water, and ensures a clear signal in both high and low conductivity conditions.




Model 102M Probes are designed for flexibility. The probe tips use a recessed design to minimize false signals in cascading water. 

P4 0.157" dia. x 1.5" long (4 mm x 38 mm) stainless steel weighing 0.35 oz (10 g). It is ideal for accessing narrow

diameters, especially the channels of a Solinst CMT System.

P10 3/8" dia. x 2.75" long (10 mm x 70 mm) stainless steel with 10 stainless steel weights, weighing 6.14 oz (174 g). This heavier probe assembly 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). A braided copper outer conductor gives flexibility and a stranded stainless steel central conductor gives strength. It is easy to repair and splice.

Other Options 

Carrying Bag Small and mini padded nylon carrying bags are available, as optional extras. The bag design has a convenient shoulder strap, zippered front pocket, zippered top, and a grommet in the base to prevent moisture build-up. A mini bag has no pocket.

Replacement Parts: Replacement cables with probes, weights, and other spare parts are available.


Tape Guide/Datum

The tape guide can be used to protect the cable from damage on rough edges, help the probe hang straight in the well, and ensures consistent measurements. It can also provide reel support on the casing. A tape guide is provided with each standard reel.
