OPTIWAVE-M 7400: The Marine Measurement Masterpiece

The OPTIWAVE-M 7400 is a state-of-the-art 2-wire, 24 GHz radar level transmitter, specifically engineered to meet the stringent demands of the marine industry. This non-contact instrument provides continuous and highly accurate cargo level measurement, making it an indispensable tool for safe and efficient ship operations. Its core technology, Frequency Modulated Continuous Wave (FMCW) radar, delivers unparalleled reliability and precision, crucial for critical ullage indication. Unlike many conventional sensors, the OPTIWAVE-M 7400 is built to withstand the harshest marine conditions, featuring a heavy-duty stainless steel housing that protects its delicate internal components from corrosion and physical damage. Its design prioritizes operational continuity, allowing for the replacement of the signal converter even during ongoing cargo operations, a feature that significantly minimizes downtime and enhances vessel productivity. The OPTIWAVE-M 7400 represents a leap forward in marine level measurement technology, offering a robust, reliable, and user-friendly solution for all types of vessels.

Engineered for the Roughest Marine Conditions

The maritime environment is notoriously challenging, characterized by extreme weather, corrosive saltwater, and constant motion. The OPTIWAVE-M 7400 is purpose-built to thrive in this demanding setting. Its rugged stainless steel housing, made from grade 1.4404 / 316L, provides exceptional resistance to corrosion, ensuring long-term durability and performance. A key feature of its rugged design is the inclusion of display protection, which shields the local ullage/level indicator from physical impact and environmental damage. This redundancy ensures that critical level information is always accessible on deck, even if the primary communication systems are compromised. Furthermore, the instrument is designed with an integral Inert Gas Pressure (IGP) sensor, which is part of the radar flange. This feature is crucial for monitoring tank pressure in inerted cargo spaces, adding an extra layer of safety and operational efficiency. The OPTIWAVE-M 7400’s robust construction and specialized features make it the ultimate choice for reliable and safe operation on any vessel, from chemical tankers to bulk carriers.

Specialized Antennas for Diverse Cargoes

The OPTIWAVE-M 7400 offers two primary antenna options, each tailored to specific cargo types and operational needs. The Horn antenna, made from stainless steel (1.4404 / 316L) or higher Molybdenum on request, is ideal for a wide range of liquids and provides a built-in purging system. This system allows for the antenna to be cleaned without opening the tank, a critical feature for maintaining hygiene and preventing product buildup, particularly with viscous or crystallizing liquids. The Drop antenna, made from PP or PTFE, is the perfect solution for measuring sticky or contaminating liquids and is also highly effective in dust-laden atmospheres, where product buildup on the antenna is a significant concern. The non-intrusive design of both antennas, with no moving parts, ensures minimal maintenance and maximum reliability. This adaptability allows ship operators to select the most suitable antenna for their specific cargo, guaranteeing accurate and consistent measurements regardless of the material’s physical properties.

Advanced Features for Unparalleled Performance

Beyond its robust physical design and versatile antenna options, the OPTIWAVE-M 7400 is equipped with a suite of advanced features that enhance its performance and ease of use. The “Tank Bottom Management” (TBM) system is a prime example of this technological sophistication. TBM utilizes dedicated algorithms to filter and compensate for irregular radar wave reflections that occur at the tank bottom when the vessel is empty. This ensures a reliable measurement even in near-empty conditions and simplifies the commissioning process, regardless of the tank’s size, material, or geometry. This feature is particularly valuable for partial cargo operations and for quick and easy setup on different vessels. The device’s impressive accuracy of ±2 mm / 0.1″ uncertainty sets a new standard for precision in marine level measurement, providing a level of detail that is essential for accurate inventory management, cargo transfer, and safety protocols.

Dedicated Applications Across the Marine Industry

The OPTIWAVE-M 7400 is a versatile instrument with a wide range of dedicated applications across the marine industry. It is a vital component in crude oil tankers, where it provides accurate ullage and level measurements for safe and efficient loading and discharging of cargo. In chemical tankers, the device’s robust materials and non-contact technology ensure the safe handling and measurement of a vast array of corrosive and hazardous chemicals. The Drop antenna option makes it particularly suitable for product tankers carrying sticky or viscous products like asphalt or molasses. For liquefied gas carriers (LGCs), the OPTIWAVE-M 7400 is essential for monitoring the levels of liquefied petroleum gas (LPG) and liquefied natural gas (LNG), where accurate measurement is critical for safety and thermal management. Furthermore, it can be used for level monitoring in ballast water tanks and slop tanks, helping ships comply with environmental regulations and manage waste efficiently. Its ruggedness and accuracy make it an ideal choice for offshore platforms and FPSOs (Floating Production, Storage, and Offloading units) as well.

The Strategic Advantage of 24 GHz Technology

The 24 GHz operating frequency of the OPTIWAVE-M 7400 provides a significant strategic advantage in marine applications. While not as high as 80 GHz, this frequency strikes an optimal balance between signal penetration and beam focusing, making it ideal for the marine environment where diverse cargo types and potential contaminants are common. The 24 GHz signal can effectively penetrate through dusty or vapor-laden atmospheres within the cargo tank, ensuring a clear reflection from the liquid or solid surface. This frequency is also less susceptible to interference from minor internal tank structures or agitation compared to lower frequencies. The careful selection of 24 GHz ensures that the OPTIWAVE-M 7400 can deliver its high-accuracy measurements reliably, even when faced with challenging on-board conditions and varying cargo properties.

Simplifying Maintenance and Ensuring Safety

The OPTIWAVE-M 7400 is designed to simplify maintenance and enhance safety, two key priorities in marine operations. The ability to replace the signal converter at any time, even during cargo operations and without opening the tank, is a groundbreaking feature that minimizes operational disruption. This “hot-swap” capability is invaluable in an industry where time is money and unexpected downtime can be extremely costly. The device is also certified by all major marine classification societies, including ABS, BV, CCS, DNV, GL, KR, LR, NK, and RINA, ensuring its compliance with the highest safety and quality standards. This extensive list of approvals provides shipowners and operators with the confidence that the OPTIWAVE-M 7400 is a reliable and safe component of their vessel’s operational and safety systems. Its robust diagnostic capabilities and compliance with ingress protection standards (IP66/67) further contribute to its low maintenance and high safety profile.
