The radar signal travels down to the surface and back. Because it does not depend on contact with the liquid, it can keep working through vapour, dust and changing surface conditions.

The higher operating frequency and shorter wavelength suit solid-state applications, and the lens-focused beam performs reliably in high-dust environments and process temperatures up to +200 °C. The transmitter mounts by thread or flange for straightforward installation.
The narrowest beam on offer minimises the impact of vessel internals, so aiming rarely needs a special flange.
Self-developed millimetre-wave chips give a smaller footprint, a higher signal-to-noise ratio and a smaller blind spot.
A 5 GHz working bandwidth delivers higher measurement resolution and repeatable accuracy.

A lens antenna cover, anti-corrosion antenna, antenna heat dissipation paste and quartz isolation flange plate are available as order-time options.
Both versions share the same sensing core and performance parameters. Choose the connection that matches the nozzle.
Compact thread connection for direct mounting on smaller nozzles and pipe fittings.
Flanged process connection for larger vessels and standard-flange nozzles.
Share the vessel geometry, medium, dielectric constant, temperature and nozzle details. We will confirm the radar configuration and mounting.
