Comparing Free-Space And Guided Wave Radar For Challenging Chemical Environments

Safe, accurate measurement of liquid levels in chemical storage tanks and processing vessels is crucial to process control and inventory management in several industries. However, corrosive materials, extreme temperatures and pressures, vapors, turbulence, and/or foam all can wreak havoc on measurement accuracy and instrument integrity.

Free-space radar and guided wave radar (GWR) systems designed for chemical service are available in a range of materials and safety certifications to enable level measurement within several industries, so it is critical to align the system type and its composition with the use environment. Additionally, elements including the required accuracy, the media’s chemical properties, tank operating conditions, and tank geometry also impact the decision.
