BRILON - Humana Milchunion in Everswinkel stores milk powder in a 60t outdoor silo. Due to the poor flow abilty of the powder it was very difficult to control the amount of product dosed into the trucks.
Different tests to improve the inventory control with level measuring systems had failed because of the angle of repose, bridge building or sticking.
Within four hours the silo was fitted with temperature compensated straingauge sensors. The sensors had been bolted directy to the vertical legs of the silo.

The sensors measure the tension/compression caused by unload or loading the silo and convert this into a linear proportional voltage signal.
The separate evaluation electronics amplifies the signal and displays the silos content directly in tons. Due to the high precision of the strain gauge transducers it is possible to load silo trucks within a tolerance of 100 - 200kg.
