Water Level Meter
For measuring the depth of water in wells, boreholes, and standpipes, the Model 101 Water Level Meter 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. Conductivity and temperature profiling accessories are available for models fitted with a P4 probe. Also available is the less expensive Model 102 Coaxial Cable Water Level Meter for use in small diameter tubes.

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.

Reels
Standard reels are ergonomically designed for good balance and ease of use, with a stand-alone design, convenient carrying handle and an excellent brake. They are robust and smooth running. The battery is housed in a convenient battery drawer and each reel has a probe holder and brake. The reels are equipped with an on/off sensitivity switch, light, buzzer, and a battery test button.

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.

PROBE OPTIONS:

















P2 Stainless Steel: with a neoprene strain relief. Size: 0.5" dia. by 7.5" long (12.7 mm x 190 mm).
P4 Environmental: stainless steel probe required for use of C4/T4 profiling sleeves. Pressure-sealed probe pulls apart for easy cleaning and decontamination and to accept C4 and T4 sleeves. Size: 0.625" dia. by 8.625" (15.9 mm x 220 mm).
P5 Submersible: stainless steel, leak-proof probe. Simple design is easy-to-clean, hangs straight in the well, and has almost zero water displacement. Size: 0.5" dia. by 8.625" long (12.7 mm x 220 mm).
C4 Conductivity Sleeve allows profiling of conductivity with depth. Low maintenance conductivity cell in sleeve slips over the P4 probe body. Analog readout plugs into the reel faceplate.Range: 0-80,000mS/cm. Depth:1250ft. (400m) Size: 0.75" dia. by 13.875" (19.05 mm x 353 mm).
T4 Temperature Sleeve allows profiling of temperature with depth. Sleeve enclosing a thermistor slips over the P4 probe body. Readout plugs into reel. The T4 Sleeve may be used with the analog Conductivity and Temperature Readout, or the Solinst digital multimeter. Range: -50°C to +150°C. Depth:1250ft. (400m) Size: 0.625" dia. by 8.75" (15.9 mm x 222 mm).
OTHER OPTIONS:







Power Reels: Power reels can be very useful to allow faster or less strenuous operation of longer lengths of tape. The 110 volt power reels are available on request.
Carrying Bag: Padded nylon carrying bags are available, as an optional extra. The sturdy design has a convenient shoulder strap, zippered front pocket, zippered top, and a grommet in the base to prevent moisture build-up.
Replacement Parts: Replacement probes, tapes with probe and other spare parts are available.
