Complete solutions for overfill prevention

According to the German Water Directive (WHG), containers for water-hazardous liquids must have overfill prevention systems. These systems monitor the level and trigger an alarm before the permitted level is reached. The WHG is thus one of the most important laws for environmental protection and to ensure operational safety. The application of, and compliance with, this law is monitored by organizations such as the Technical Inspection Authority TÜV.

Reduce costs and save time.

How? With Endress+Hauser as your partner, you will benefit from a comprehensive solution covering all aspects of the WHG: design, calculation, field devices, engineering, switch cabinet assembly, installation, commissioning, seminars, and services all from a single source. The fastest method of proof testing is using the proof test button when the device is installed. Proof-testing is not required for up to 12 years using Endress+Hauser's latest system.
