An existing tower silo at the IMAG experimental dairy farm was instrumented with pressure measuring panels and a second bottom on four load cells. The panels were of the type developed by Hierlein (Braunschweig, Germany). Changes had to be made to prevent gas- and effluent leakage and to correct the movement under load. Both the lateral and the vertical (that is frictional) forces could be measured, as well as the fluid pressures in the case of exceeding the saturation density. The silage effluent, which drained through a narrow gap between the silo wall and the second bottom, was led to a sump and measured. The instrumented silo was filled in 1978 and in 1979. Each year once with grass and later with corn. Generally speaking calculations based on the silage characteristics, obtained in the laboratory, predicted the measured pressures adequately.
