RF Series 80 GHz for Narrow Liquid Tanks

The RF Series is a two-wire 80 GHz FMCW radar level measurement transmitter. This measuring device suits challenging liquid level applications involving narrow tanks with long nozzles and internal obstructions such as agitators, ladders or heating coils. The minimal beam angle and dead zone make this an optimal choice for continuous, non-contact level measurement in both very small and very high tanks (up to 100 m/328 ft).

This level transmitter can also measure through tank roofs made of non-conductive materials, to provide users with additional mounting options.

The RF Series provides accurate readings, even in processes that have fast-changing levels. The PEEK lens antenna is resistant to build-up and well-suited to corrosive environments. As the antenna is flush-mounted, there is no intrusion into the tank.

Operating temperatures are up to +150°C/+302°F, with pressures up to 40 bar/580 psi. The RF Series offers a range of flange and thread connections, starting from just ¾". It comes with approvals for use in hazardous areas as well as extensive device diagnostics (acc. to NE 107) and HART®7 communication.
