Special challenges:
Changing media with varying properties, build up


Semi-liquid manure, or slurry, in biogas plants is often stored in closed, large-volume slurry tanks. Through fermentation, a valuable energy carrier is extracted from the mixture of organic waste and renewable raw materials. Level and pressure are monitored in the tank, as well as in the delivery and removal systems handling the raw materials and waste.

Your benefit

Reliable operation of the fermenter through overflow protection
Cost effective
Universally applicable and modular sensors across the biogas plant, thus very cost-effective spare parts stocking
User friendly
Maintenance-free operation using build up-insensitive technologies
