Case Study: Not All Guided Wave Radar is Created Equal

One of the world’s largest oil & gas and petrochemical companies,  was having problems with multiphase applications involving hydrocarbon level with water bottoms and gas vapor space. Guided wave radar (GWR) technology was introduced to monitor these applications. However, the GWR devices selected did not produce a reliable signal throughout the measurement range, and the dynamics of the interface made it difficult to distinguish between the upper level and the water below. There was a threat of loss of primary containment (LOPC) due to these measurement errors.

MAGNETROL pioneered GWR technology for level measurement and its latest device, the Eclipse® Model 706, is considered the highest performing GWR level transmitter on the market.  The ECLIPSE Model 706 was tested side-by-side with multiple GWR competitors for both top level and interface measurements and it was proven to be best-in-class.  The ECLIPSE 706 tracked level up to the device’s flanged process connection, above 100% level, as there are no dead zones or blind spots at the top of the probe.  It prevented LOPC by tracking the top hydrocarbon level through the vapor space and also measured the interface (water bottom) due to the superior signal strength. In summary, it was the only device tested that could produce reliable measurements with a completely dry probe, a probe having only one of the two process media present, and under varying interface conditions.
