Guided Wave Radar (GWR)
Radar level measurement where the microwave signal travels along a probe.
IN ONE SENTENCE
Reflections from the product surface are analysed to determine level.
In normal English
Guiding the signal along a rod or cable can make GWR very effective in vessels, interfaces and conditions where free-space radar is less convenient.
Why would I use it?
Use it for tanks where a contacting probe is acceptable and strong guided reflections are desirable.
THINK OF IT LIKE…
Radar travelling down a physical rail into the product.
