Water Level Logger


Water Level Logger


The Automatic Water Level Logger is a sophisticated unit for automatically recording water height at pre-programmed time intervals for up to two years. It can be used for measuring soil conductivity, monitoring the height of water in rivers, or measuring flow rates etc. The data is downloaded directly onto a PC without the need of further equipment. The software provides a graphical display of the water level. It also gives the maximum and minimum values, and allows the user to export the data into a spreadsheet. The probe has been redesigned so that it can be placed directly into the water without the need of a protective tube. The unit includes a robust protective housing.
