Solinst Model 201 Water Level Temperature (WLT) Meters

Overview

The Model 201 Water Level Temperature (WLT) Meter is ideal for measuring static water levels, as well as profiling temperature in wells, boreholes, tanks and open water.

Accurate temperature measurements are clearly displayed on an LCD readout on the faceplate, from -20°C to +125°C.

Water level and probe depth measurements are read off the Solinst durable PVDF flat tape. Tape lengths are available up to 2000 ft (600 m).

Also from Solinst, the Model 107 TLC Meter measures water level, temperature and conductivity. For automated water level and temperature data logging, Solinst also offers the Model 3001 Levelogger Edge.

Laser-marked PVDF Flat Tape

The WLT Meter uses extremely durable PVDF flat tape. The tape is non-stretch and has a dog bone design that prevents adherence to wet surfaces. The tape reels smoothly, remains flexible and hangs straight, regardless of temperature. It is also easy to repair and splice.

The 3/8" (10 mm) wide tape has permanent laser markings every 1/100 ft. or each millimeter, traceable to NIST and EU measurement standards.

Water Level & Temperature Probe

The 201 Probe is made of high quality 316 stainless steel. The pressure-proof probe can be submerged to 1000 ft (300 m). The zero measurement point on the probe is close to the tip, keeping water displacement at a minimum.

The temperature sensor is located at the stainless steel tip of the probe, however, since the probe body acts as a heat sink, best accuracy is obtained when the probe is completely submerged. The tape seal plug design allows the probe to be easily replaced, if required.
