Radar Level Meters

Radar level meters are selected when non-contact measurement is needed and ultrasonic echo reliability is uncertain. Common reasons include vapor, foam, dust, pressure, temperature variation, long range, low dielectric media or difficult outdoor water applications.

80 GHz free-space radar uses a narrow beam, which helps with small nozzles, tall silos, internal structures and dusty bulk solids. The correct configuration still depends on antenna style, process connection, beam path, false echo suppression and the material surface.

Guided wave radar is different from free-space radar. It uses a rod, cable or coaxial probe and is often reviewed for narrow tanks, bypass chambers, low-dielectric liquids, interface service and conditions where non-contact radar may see unwanted echoes.

For silos, send height, diameter, cone geometry, nozzle position, filling point, material name, dust level and whether air purge is available. For liquids, send tank height, medium, dielectric, foam, vapor, pressure, temperature and hazardous-area requirement.

WELK writes radar pages as configurable product families rather than fixed model pages. Final measuring range, accuracy class, output, pressure rating, temperature rating and approval wording must be confirmed from the ordered configuration.
