Water Level Meters

Advantages

Audible and visible alarms activated when the probe makes contact with water. Adjustable sensitivity to maximise efficiency with robust construction for the accurate detection and measurement of water level in the most rugged of field conditions.

Simple, fast and easy to use
Robust construction and light weight
Available in 30m, 50m, 60m and 100m lengths and longer to order
Audible and visible alarms activated on reel when probe contacts water
No disturbing parts when inserted into a borehole
Variable cable lengths from 5 to 1,000 m
15 mm diameter probe.

Applications

Water level measurements of electrically-conducting liquids in boreholes, wells and tanks (in ATEX- free zones only)
Long-term observations for periodic level soundings
Continuous water level registration during pumping tests
Additional sounding of well depths using the bottom sensor (accessory)
