| For measuring the depth to water in wells, boreholes, standpipes,
and tanks, Model 101 Water Level Meters are the industry
standard for portable hand operated meters. They are sturdy,
easy to use and read accurately to 1/100 ft. or each millimeter. There are two versions to choose from. The Model 101 P7 Water Level Meter features a pressure-proof probe rated to 500 psi and laser marked PVDF tape. The Model 101 P2 Water Level Meter features an easy-to-repair probe and heat embossed polyethylene tape. Also available, is the less expensive Model 102 Coaxial Cable Water Level Meter for use in small diameter tubes, and the 102M Mini Water Level Meter on a small, compact reel |

| Operating Principles |
| Model 101 Water Level Meters use corrosion proof stainless
steel probes attached to permanently marked flat tape, fitted
on a well-balanced reel. They are powered by a standard 9 volt
battery. The probes incorporate 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. A sensitivity control allows the buzzer to be turned off while in cascading water, and ensures a clear signal in both high and low conductivity conditions. |
| Reels |
| With a stand-alone design, convenient carrying handle, and
sturdy probe holder, the standard reels are ergonomically
designed for ease of use. They are robust and smooth running. The battery is housed in a convenient drawer in the front of the reel, allowing quick replacement. The reels are equipped with an on/off sensitivity switch, light, buzzer, battery test button, brake and a tape guide stored on the frame. |
| PVDF Laser Marked Tape |
The Model 101 P7 Water Level Meter uses extremely durable,
PVDF flat tape, traceable to NIST and EU measurement
standards. Each tape conductor contains 13 strands of stainless
steel, and 6 strands of copper-coated steel, making the tape
non-stretch and high in tensile strength and electrical efficiency. |
 LM2: Feet and tenths: with markings every 1/100 ft. LM3: Meters and centimeters: with markings every mm |
| P7 Probe |
The P7 Probe is submersible up to 1000 ft. (300 m), ideal
for measuring total well depth. The sensor at the tip of the
probe provides consistent measurements with almost zero
displacement. The tape seal plug design allows the probe to be
quickly and easily replaced, if required. |
| Features |
Accurate: • Markings each 1/100 ft. or millimeter |
| P2 Probe |
The P2 Probe is shielded in design to reduce or eliminate false
readings in cascading water. The probe consists of a stainless
steel body with a neoprene heat shrink seal. It is not suitable for
submergence to any significant depth. Its simple design makes
it easy to repair. |

|
| Polyethylene Tape |
The Model 101 P2 Water Level Meter uses high quality
polyethylene tape that reels smoothly, remains flexible and hangs
straight in the well. Heat embossed marking each millimeter or
1/100 ft. allow accurate readings. The 3/8" (10 mm) wide tapes
come in lengths up to 6000 ft. (1800 m). |
 M2 Feet and tenths: with markings every 1/100 ft. M3 Meters and centimeters: with markings every mm |
| Other Options |
Power Reels: Power reels can be very useful to allow faster or
less strenuous operation of longer lengths of tape. Carrying Case: Small and medium padded nylon carrying cases are available, as an optional extra. Their 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 and other spare parts are available. |
| Tape Guide/Datum |
| A tape guide is provided with each 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. |  |
