Geotech open standpipe filter unit for ground water level measurements has a sintered bronze filter and can normally be directly pushed into the soil without pre-drilling.
The filter unit is used together with 1" tubes and a piezometer unit or a portable water level meter.
It is also possible to use a hose for quicker detection of ground water changes. The hose is connected to the filter unit and the water level is measured in the hose which is only 8 mm in diameter. For this application we offer a water level meter with a coaxial cable for lowering into the hose.
Different types of water level meters are available on request:
