Guided Wave Radar
Highly accurate and reliable level and interface measurements with easy installation.
Guided wave radar devices have no moving parts and require minimum maintenance. They can measure both level and the interface between two media.
The technology is not affected by media density, varying temperatures or pressures, and provides reliable, accurate measurements in demanding applications.
Guided wave radar is based on microwave technology. Microwaves are only affected by materials that reflect energy which means that temperature variations, dust, pressure, and viscosity do not affect accuracy.
The device sends a low energy microwave pulse down a probe. When the pulse hits the media, a significant proportion of the energy is reflected back up the probe to the device. The level is directly proportional to the time-domain reflectometry. Because a proportion of the emitted pulse will continue down the probe, an interface can also be detected.
