Measuring fill level and interface with Yo-Yo sensing system
The MOLOSbob LF20 enables simple level measurement in silos and bunkers up to 42 m. With the aid of different sensor weights, the Yo-Yo system delivers reliable measurement results regardless of the bulk solids properties and thus without complex parameterization. The measured value is output as a 4-20 mA signal and visualized via display instruments. In the LF20-T version, the MOLOSbob is also used for interface measurement.
