Guided Wave Radar: Today's Vanguard In Level Measurement

Guided Wave Radar (GWR), the increasingly popular, industrial, loop-powered transmitter we know today, burst on the scene in the late 1990s. The Magnetrol® Eclipse® Model 706, like most devices, is based on the revolutionary Lawrence Livermore National Lab patent that in 1995 Popular Science magazine called “Radar on a Chip” for $10.

At first the Eclipse GWR was almost shunned. Why would a customer use an “RF capacitance-looking device” with a probe? Non-contact devices had clear advantages over contact with ultrasonic and radar transmitters already carving out their own niche in the marketplace. Installing a probe seemed almost archaic. But, the probe WAS the secret.
