New Guided Wave Radar Transmitter Delivers Accurate Level Measurement In Harsh Processing Conditions

Magnetrol’s Eclipse® Model 700 Packs Industry-Leading Technology Into Economical Design

Apr. 14, 2020 ­- AURORA, Ill – Magnetrol, a global leader in level and flow measurement instrumentation, has launched the Eclipse® Model 700 Guided Wave Radar (GWR) transmitter. This new level measurement solution is designed to be virtually unaffected by changing media conditions, including turbulence, foaming, boiling, and flashing.

“The Eclipse Model 700 continues our tradition of bringing innovative, high-ROI solutions to the market,” says Bob Botwinski, Sr. Global Product Manager at Magnetrol. “All Eclipse models are able to measure and control media in challenging applications with unprecedented accuracy while providing proactive diagnostics to the user.”

Proactive diagnostics, like the Model 700’s build-up detection feature, minimize maintenance costs by allowing engineers to proactively schedule shutdowns and maximize uptime.

Magnetrol pioneered loop-powered GWR transmitters for industrial liquid level applications in 1998 with its Eclipse Model 705, and the company remains the leader in application and technology expertise.

Eclipse GWR solutions, including the new Model 700, are designed to handle any level of complexity and are equipped for overfill protection through the industry-leading probe design that allows for level measurement across the entire probe length with a smaller dead zone than any competitors.

The Model 700 also features true level measurement and boasts the market’s highest signal-to-noise ratio.  Together, these features enable the Model 700 to achieve direct measurement of material levels, including liquids, foams, and solids – even distinguishing between liquid and foam layers.
