Radar Level Meter


KROHNE, Inc. introduces the OPTIWAVE 5200 C/F, a new 10 GHz FMCW radar level meter for liquid applications in up to a 30m / 98 foot measuring range. The cost effective 2-wire loop powered device measures level and volume in storage or process tanks with process conditions up to 250°C / 482°F and pressures up to 40 bar / 580 psi. for general purpose or hazardous locations. (Class 1/Div 1) Together with the recently launched OPTIFLEX 2200 C/F TDR level meter, the OPTIWAVE 5200 C/F has been designed and developed for use in SIL 2 safety-related systems according to IEC 61508. 

The OPTIWAVE 5200 C/F electronics are compatible with a wide selection of antennas. The unique PP and PTFE Wave Horn antennas are process sealed by their antenna material instead of a traditional process seal construction with “O” ring gaskets. These gasket free antennas are ideally suited for extremely corrosive environments. The PP antenna can be mounted on process connections as small as 1 ½ inch. The metallic horn and waveguide antennas use a dual seal mechanism, which is a combination of “O” ring gaskets with KROHNE’s unique Metaglas process interface design, for a completely hermetic seal in highly toxic or explosive applications. Metallic horn antennas range in sizes from DN 80…200 / 3…8”. 

The modular design of the housing with its unique bayonet locking system and antenna extensions ensures suitability for a variety of mounting positions and applications. To make the display screen easy to read, the quick coupling system permits 360° housing rotation. The housing can also be removed under process conditions. The remote converter version OPTIWAVE 5200 F features full display and configuration capability up to 100 m / 328 feet away from the antenna. Fully compatible with all installed KROHNE BM 70 flange systems, this new meter can also upgrade any BM 702 radar level meter with enhanced measurement performance  and features and is compliant to newer requirements such as SIL and NAMUR guidelines. This new unit offers 4…20 mA with HART communication and PACTware DTM’s at no extra charge.
