Buffer silo for raw materials in the ethanol plant

Level measurement and point level detection in buffer silos

Level measurement and point level detection in buffer silos
Level measurement and point level detection in buffer silos

Process data

Measuring task:
Level measurement and point level detection
Measuring point:
Measuring range up to:
15 m
Process temperature:
-20 … +40 °C
Process pressure:
0 … 0 bar
Special challenges:
Extreme mechanical loading of all components, high dust generation, continuous operation


In order to always have enough material available for downstream processes in the ethanol plant, the crushed raw materials are held ready to use in buffer silos. The ground-up grain ‘flour’ for the production of ethanol is transported directly from the mill into a silo, where it is temporarily stored. The vast material throughput can lead to extreme mechanical loading of the silos and the associated equipment and high levels of dust are generated in the process. Level sensors are deployed to optimise the throughput, reduce overloading and ensure continuous, economical production and operation of the plant.

Your benefit

The measuring systems protect against mechanical overload, thereby ensuring smooth, trouble-free operation
Cost effective
Enabling smoother continuous production guarantees economical operation
User friendly
In case of extreme dust build up on the sensor, automatic cleaning can be enabled via the air purge connections on the sensor
