What do you do to prevent storage tank overfill?

We deliver an unrivaled solution that addresses the entire safety loop

Storage tanks often contain liquids that are environmentally unsafe. If not properly monitored, serious incidents can occur - such as injury to your personnel. Something as simple as a faulty float switch can cause problems if it fails to alarm when fluids reach an unsafe high level in the tank. Vapor clouds can form when there is a spill which can lead to explosions and fire. So, overfill prevention systems are a must - but they can be costly, tedious to implement and difficult to maintain.

Reduce your commisioning time and maintenance costs


Our pre-configured solution package reduces project costs by up to 20% and lowers implementation risk as it is based on a standard approach with repeatable designs - tested and documented. Jointly developed with Rockwell Automation, it resulted in a complete and integrated solution able to address the entire safety loop, from measuring and monitoring to correcting elements. Devices are pre-integrated, only on-site parameterizing is needed, and the whole solution is modular and expandable.
