New radar level transmitter for liquids

Jon Lawson

Krohne has introduced the Optiwave 1400 FMCW radar level transmitter for the water and wastewater industry. The new 24 GHz device features all the benefits associated with FMCW radar technology – high accuracy, reliability and measurement stability.

It’s designed for liquid level measurement applications across the water industry, for example in extraction, transport, storage and distribution of water from springs, rivers, lakes or the sea, as well as in rainwater basins. Typical applications in the wastewater industry include level measurement of wastewater, sludge or other liquids in storage applications or pumping stations. It can also be used for level measurement through plastic tanks (e.g. IBC), as well as open channel flow measurement, or floodwater alarm.

It features the proven polypropylene (PP) Drop antenna with the smallest beam angle (8°) on the market. The 2-wire 4-20 mA (HART 7) transmitter provides accurate and reliable level measurement up to 20m/66ft despite condensation, turbulent surfaces or foam. It comes with a robust stainless steel housing and IP68/ NEMA 4X/6 rating. It is maintenance-free and designed for simple and safe installation and operation. Delivered with reinforced cable gland and 10 m/ 33 ft cable, the new water radar offers thread as well as low-pressure flange connections and various other accessories.
