OPTIWAVE-M 7400
Radar (FMCW) level transmitter for liquids and solids in the marine industry
- Continuous, non-contact cargo level measurement
- 24 GHz radar, Horn or Drop antenna
- Redundant ullage indication with local display on deck
- Closed tank cleaning and service of all components
OPTIWAVE-M 7400 with DN100 / 4" PP Drop antenna
The OPTIWAVE-M 7400 C is a 2-wire 24 GHz radar (FMCW) level transmitter for non-contact cargo level measurement. This marine level radar is a highly accurate and reliable instrument for ullage indication. Equipped with heavy-duty stainless steel housing, it is designed to withstand the roughest conditions on ships. If necessary, the signal converter of the level transmitter can be replaced during cargo operations. The Drop antenna option makes it ideal for measuring sticky/contaminating liquids or dust-laden atmospheres where product build-up is likely to occur.
The extremely rugged cargo radar features a backup display for redundant indication. Cargo operations may continue with a man on deck, if level information is lost on the main monitoring station. The OPTIWAVE-M 7400 level transmitter is the perfect fit for applications with the CARGOMASTER® solution for onboard tank monitoring and alarm. It holds IEC (Ex IIC) intrinsic safety certification as well as approvals of all major marine classification societies.
Product highlights
- Cargo radar level gauge designed to operate in the roughest marine conditions
- With rugged stainless steel (1.4404 / 316L) housing and display protection
- Redundant display: ullage/level will always be shown locally
- Inert gas pressure sensor (IGP) integral part of radar flange
- Antennas:
- Horn antenna (DN100 / 4"): Stainless steel (1.4404 / 316L) or higher Molybdenum (on request)
- Drop antenna (DN80 /3" or DN100 /4"): PP or PTFE
- Horn antenna option comes with built-in antenna purging system for cleaning without opening the tank
- Replacement of the signal converter can be done at any time, even during cargo operations without opening the tank
- Accuracy: ±2 mm / 0.1" uncertainty
- Optimized for use with the CARGOMASTER solution for liquid cargo monitoring and alarm
