Safe, cost-effective level measurement

Endress+Hauser non-contact radar measures level in corrosive chemical tanks

A U.S. water treatment plant operating at 85 MGD capacity was in need of a measurement technology that would accurately and safely measure level in corrosive chemical bulk storage tanks.

Your benefits

  • Improved process safety due to gastight feedthrough

  • Reduced wiring costs due to 2-wire technology allowing easy implementation into existing system

  • Accurate measurement independent from product properties

Customer challenge

The plant was in need of accurate and reliable level measurement for chemical tanks with product density variations due to temperature changes, without the high costs associated with chemical compatibility issues. Ultrasonic level devices are common in these applications. Therefore, the technology had to be both non-intrusive and non-contact. Differential pressure devices were also considered, however, due to high costs of exotic materials for wetted parts, this option was ruled out.

Our solution

We installed the Micropilot FMR53 non-contact radar device to measure the level in the corrosive chemical tanks. The FMR53 was a good fit for this application as the Micropilot is not affected by different product properties such as changing dielectric, HF fumes, caustic corrosion and changing specific gravities which was present in these corrosive chemical storage and day tanks.
