Water Level Temperature Meter

Water Level & Temperature Probe

The 201 Probe is made of high quality 316 stainless steel. The pressure-proof probe can be submerged the full length of the tape. The zero measurement point on the probe is close to the tip, keeping water displacement at a minimum. A probe shroud protects the sensor tip.

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.

Water Level & Temperature Applications

Water temperature has a direct affect on the biological activity of aquatic plants and animals, as well as many aspects of water quality and chemistry; therefore, it is an important parameter to monitor.

The Model 201 Water Level Temperature Meter is ideal for:

• Profiling temperature in wells and open water
• Detecting runoff, points of inflow, or other sources of thermal pollution
• Early warning of changes in water quality, including dissolved oxygen levels and conductivity
• Monitoring and predicting changes in aquatic environments
• Geothermal drilling and studies

Laser Marked Flat Tape

The Water Level Temperature Meter uses extremely durable 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.

• LM2: Feet and tenths: with markings every 1/100 ft.
• LM3: Meters and centimeters: with markings every mm

Water Temperature Display Menu

When the meter is turned on, the LCD screen displays the firmware version of the WLT Meter (e.g. "WLTM 1.0") for about two seconds. The LCD will then display the temperature reading, in or out of water.

The LCD menu is simple to operate. Pressing the button two times quickly deactivates the buzzer (the light stays active). To reactivate, press the button two times quickly. To turn the meter off, press and hold the button for two seconds.
