Process data
Measuring task:
Level and pressure measurement
Measuring point:
Tank and pipeline
Measuring range up to:
5 m

Special challenges:
Hygienic production conditions
Application
High-purity water (WFI) is required for pharmaceutical products that are injected directly into the bloodstream or administered as eye or nose drops. This water is produced through filtration and distillation, then stored temporarily in tanks. Absolute sterility and cleanability are essential criteria for all process components that have direct contact with the medium. This also applies to the instruments for level and pressure measurement in the tank.
