Water–Level values are measured by an oil free titanium reference pressure measuring cell which senses a hydrostatic pressure of the
water column by a pressure with a capacitive diagram and converts this value into an electrical signal.Then measuring values are stored in
data logger which is built into the body of the pressure probe.
The PSL-037 Water Level Recorder with GE-Druck–PDCR/1830 pressure probe is especially designed for the continuous recording of
ground water level , surface water level , waste water level and tank level.
In pipes and bore holes of small diameter ( 2’’ ).
In large depths ( max. 300 m , up to 600 m ).
Not exactly in vertical bore holes or pipes.
For water level measurements are not permanently in water carrying river beds.( wadis , storage basins , etc. )
