Using through-air radar on low dielectric materials in petroleum industry applications

Recently, a refinery customer came to use with a level application. Our team determined that it would be a perfect fit for radar level gauges, IF they turned on a Siemens radar algorithm called CLEF, that would let the radar measure accurately all the way to the bottom of the tank.

What is CLEF? How does it work? And why does it matter?
