WLM FaceplateThe Geotech Portable Water Level Meters + Temperature are designed to provide reliable and accurate measurements of groundwater levels and temperature. Readings are conveniently taken at the top of the casing with accuracy to within 1/100 of a foot and ± -0.5°C (temperature accuracy).

The sensor on the WLM consists of a stainless steel and PTFE probe attached to a reel-mounted, PVDF-coated engineer’s tape. The engineer's tape comes in standard or metric graduations, and is accurate to 1/100th of a foot, or 1 millimetre.
 
The sensor relies on fluid conductivity to determine the presence of water. An audible signal and visible blue LED activate when the probe contacts water, and there is a mute button to silent the signal while probing for temperature. The reel features adjustable conductivity sensitivity to prevent false triggering.
