Slurry tanks in biogas plants
Point LevelPressure

Overview
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.
Operating Conditions
- Measuring Range
- -1 ... 100 bar
- Temperature
- -40 ... 150 °C
- Pressure
- -1 ... 64 bar
Challenges
- Changing media with varying properties, build up
Benefits
- Reliable: 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
