The Model 101
Water Level Meter is used for measuring the depth of water in wells, boreholes,
and standpipes, and is the most accurate and reliable of the Solinst meters. It
is easy to operate and read to 1/100 ft. or to each millimeter. Also available
is the less expensive Model 102 Coaxial Cable Water Level
Meter for use in small diameter tubes.
The Mini
101 Water Level Meter is
ideal for use in narrow diameter applications as small as 3/8" (10 mm).
The narrow 1/4" (6 mm) tape is
mounted on a convenient small reel that is light weight and fits easily into a
backpack. The accurate, flat white tape is marked each 1/100 ft. or each mm.
The Mini 101 is available in 65 ft
and 10m lengths with a choice of the 1/4" (6mm) P1 probe, or the
heavier 3/8" (10mm) P2 probe.

Model 101 Operating Principles
The Model 101 Water Level Meter uses a choice of probe designs, attached to a permanently marked polyethylene tape, fitted on a well-balanced reel. It is powered by a standard 9 volt battery housed in an easy-access battery drawer. The conductors embedded within the tape each have seven strands of stainless steel for strength and flexibility.
The probe incorporates an insulating gap between electrodes. When contact is made with water, the circuit is completed, activating a loud buzzer and a light. The water level is then determined by taking a reading directly from the tape at the top of the well casing or borehole.

Tape Specifications
The high quality polyethylene tape reels smoothly, remains flexible and hangs straight in the well, irrespective of temperature. Permanent markings each millimeter or 1/100 ft. allow accurate readings, traceable to national standards.
Stranded stainless steel conductors resist corrosion, provide strength and are non-stretch. They make the tape very easy to repair and splice. The dog-bone design avoids adherance to wet surfaces. Markings are permanently impregnated onto one side of the tape and are available in your choice of scale or with a combination of scales.

Tape Guide/Datum
A tape guide is provided with each standard Water Level Meter. It protects the tape from damage on rough edges of well casing and ensures easy, consistent measurements, regardless of who takes the readings. It can also provide reel support on the casing.
