When the zero point of the 201 Water Level Temperature Meter Probe enters water, an electric circuit is completed, activating the buzzer and light. The depth to water is then read off the flat tape.
Temperature readings are read off the LCD display. As the probe is lowered to take temperature measurements at discrete depths, the buzzer can be turned off by pressing the button two times quickly. This is ideal when profiling temperature.
A Tape Guide allows depth measurements to be read at the marked position on the Tape Guide, to give reliable, repeatable, accurate depth measurements when profiling a well. The Tape Guide protects the tape from damage on rough edges of well casing.
Laser Marked PVDF Flat Tape
The Water Level Temperature 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.
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.
