The E+H FMR50 Radar Level Transmitter, a remarkable innovation from Endress+Hauser, has redefined the standards for continuous level measurement in industrial applications. Engineered with cutting - edge radar technology, this transmitter offers unparalleled accuracy, reliability, and versatility, making it an indispensable tool across a diverse range of industries, from chemical processing and oil & gas to food & beverage and pharmaceuticals.
At the heart of the FMR50 lies its sophisticated radar - based measurement principle. Unlike traditional level measurement methods that can be affected by factors such as temperature, pressure, vapor, and foam, radar technology operates by emitting high - frequency electromagnetic waves. These waves travel through the air or vapor space above the liquid or solid material in a vessel and reflect off the surface of the medium. The time taken for the waves to travel to the surface and back to the transmitter is precisely measured.
This non - contact measurement approach offers several significant advantages. First, it ensures highly accurate level measurements regardless of the physical and chemical properties of the measured medium. For example, in a chemical plant where the liquid may have a high viscosity, be corrosive, or prone to foaming, the FMR50 can still provide precise readings without being affected by these characteristics. Second, the radar - based measurement is immune to changes in temperature and pressure within the vessel. Whether the process is operating at extremely high temperatures, such as in a petrochemical refining unit, or under high - pressure conditions in a gas storage tank, the FMR50 maintains its accuracy and reliability.
Features
The FMR50 features a compact and modular design, combining the transmitter electronics with a variety of antenna options. The transmitter itself is housed in a durable enclosure that provides excellent protection against harsh environmental conditions. Available in materials such as aluminum and stainless steel, the enclosure offers different degrees of protection, ranging from IP66/67 (dust - tight and protected against powerful water jets) to explosion - proof ratings suitable for hazardous areas.
The choice of antenna is crucial for the performance of the radar level transmitter, and the FMR50 offers a wide selection to meet diverse application requirements. For example, the horn antenna is ideal for applications where a high - energy, focused signal is needed, such as in large storage tanks with long measuring distances. It provides good signal strength and penetration, ensuring accurate measurements even in vessels with complex geometries or internal structures. On the other hand, the planar antenna is a great option for applications where space is limited or where a low - profile design is required. It offers good resistance to buildup and is suitable for measuring the level of liquids with a relatively low dielectric constant.
Product Overview
To facilitate easy integration into existing industrial processes, the FMR50 offers a comprehensive range of process connections. Flange connections are available in various sizes and standards, including ANSI, DIN, and JIS, allowing for seamless installation on tanks, vessels, and pipelines of different specifications. Threaded connections are also provided for smaller - scale applications or where a quick and simple installation is preferred. These process connections are designed to ensure a secure and leak - tight fit, maintaining the integrity of the process and the accuracy of the level measurement.
The FMR50 is equipped with standard electrical interfaces to ensure compatibility with a wide range of power supplies and control systems. It typically operates on a 24 V DC power supply, which is commonly available in industrial settings. In terms of communication, the transmitter supports multiple protocols, including HART, PROFIBUS PA, and FOUNDATION Fieldbus. The HART protocol, for example, enables two - way digital communication over the existing 4 - 20 mA analog signal, allowing for remote configuration, calibration, and diagnostics of the transmitter. This feature significantly reduces the need for on - site manual intervention, improving operational efficiency and reducing maintenance costs.
