Lysimeters are weighed at UGT with three precision weighing cells of the accuracy class C3 / C6 and the digital weighing monitor UGT WM 100 with a large graphics- capable LCD display. The stainless steel structure made of tubular steel on B15 concrete base provide a safe base for the weighing technology. This so-called load triangle guarantees a stable and exact installation of the weighing cells as the foundation for a precise measurement. The weighing cells are installed with the assistance of shock mounts which are torque and shear-force free.
The use of shock mounts facilitates mechanical flexibility of the force input into the scales. Tensions between the weighing cells through temperature fluctuations, flection and vibrations which would lead to considerable measurement errors are therefore prevented. In addition to the centralized data acquisition the new weighing monitor facilitates direct communication with the connected lysimeter.
The uncontrolled water input as a result of rain can be prevented by a mobile roof which automatically moves over the lysimeters when it rains. Since the roof only covers the lysimeters when it rains, the influence of the roofing on the vegetation is very low. Rain systems can be installed for selective fully automatic watering. In the special case of a sloped lysimeter, it is also possible to record the surface run off.
This is captured in a collar, recorded in a tipping counter and filled into collecting flasks as required for later investigation or as an adequate sample. In the lysimeter mode, measurement curves from earlier measurement periods can be graphically displayed in addition to settings and measurement interval changes. Irregularities can therefore be recognised directly during inspections of the lysimeter.
