Product DescriptionProduct DescriptionEndress + Hauser FMI51The Endress + Hauser FMI51, part of the Liquicap M series, has emerged as a leading solution for continuous level monitoring in a wide variety of applications. With its advanced design, robust construction, and high - performance capabilities, the FMI51 has become a trusted choice for industries ranging from chemical and petrochemical to food and beverage, and pharmaceutical. This comprehensive exploration will delve into the working principles, design features, technical specifications, applications, and advantages of the Endress + Hauser FMI51 capacitive level transmitter.One of the remarkable features of the FMI51 is its independence from the dielectric constant (DC) when the liquid conductivity is 100 μS/cm or higher. For conductive liquids, the measurement is based on the electrical conductivity rather than the dielectric properties. The FMI51 can accurately measure the level of various liquids within this conductivity range without the need for recalibration when switching between different liquid types. This is a significant advantage in industrial processes where multiple liquid substances with different dielectric constants may be present in the same system.1.Design Features1.1 Probe DesignFully Insulated Rod ProbeThe FMI51 is equipped with a fully insulated rod probe, which is a key design element for its performance. The insulation of the probe serves multiple purposes. Firstly, it protects the internal sensing elements from the corrosive effects of the process media. In harsh chemical environments, where the liquid may contain aggressive substances, the insulation ensures the longevity of the probe and the accurate functioning of the sensor. Secondly, the insulation helps in maintaining the integrity of the capacitive measurement. It prevents electrical interference from the surrounding environment and ensures that the measured capacitance is solely due to the presence of the liquid being monitored.The rod probe is made from high - quality materials, often corrosion - resistant metals such as 316L stainless steel. This material choice makes the probe suitable for use in a wide range of industrial applications, including those where the liquid being measured is corrosive. The probe's surface can also be treated or coated to further enhance its resistance to build - up in applications where the liquid has a tendency to form deposits on the probe surface.1.2 Electronics and CommunicationTransmitter ElectronicsThe electronics within the FMI51 are designed to accurately process the capacitance signals from the probe and convert them into useful output signals. The transmitter electronics are engineered to be highly reliable and stable, even in challenging industrial environments. They often include advanced signal - conditioning circuits that can filter out electrical noise and interference, ensuring that the measured level signal is accurate and consistent.The FMI51 can be configured with different output options. A common output is the 4 - 20mA HART (Highway Addressable Remote Transducer) signal. The 4 - 20mA signal is a standard in the industrial automation industry, allowing for easy integration with other control systems such as Programmable Logic Controllers (PLCs) and Distributed Control Systems (DCSs). The HART protocol, on the other hand, enables two - way communication between the FMI51 and the control system. This communication allows for remote configuration of the transmitter, reading of diagnostic information, and access to additional process data.2.Advantages2.1 Reliability in Harsh ConditionsThe FMI51's robust design, with its fully insulated rod probe, corrosion - resistant materials, and high - protection - level enclosure, makes it highly reliable in harsh industrial conditions. Whether it is exposed to high temperatures, high pressures, corrosive chemicals, or dusty and wet environments, the FMI51 can continue to operate accurately and consistently. This reliability reduces the need for frequent maintenance and replacement, leading to lower overall operating costs for industrial plants.2.2 Wide Range of Approvals and CertificationsThe FMI51 has obtained a wide range of approvals and certifications, which makes it suitable for use in a variety of applications and industries. It has international explosion protection certificates, which are essential for use in hazardous areas where the presence of explosive gases or vapors is a concern. It also has certifications related to overfill prevention (WHG), functional safety to SIL2 in accordance with IEC 61508, and hygienic certificates for use in food, beverage, and pharmaceutical industries. Additionally, it may have marine approvals for use in maritime applications. These certifications provide assurance to customers that the FMI51 meets the highest standards of safety and performance in different applications.2.3 No Calibration Necessary for Conductive LiquidsAs mentioned earlier, when the liquid conductivity is 100 μS/cm or higher, the FMI51 does not require recalibration when measuring different liquids. This feature simplifies the operation and maintenance of the device in industrial processes where multiple conductive liquid substances may be present. It saves time and effort for operators, as they do not need to perform frequent calibration procedures, and it also reduces the risk of errors associated with incorrect calibration.2.4 Fast Measurement Reaction TimeThe FMI51 offers a fast measurement reaction time, which is important in applications where rapid changes in liquid level need to be detected and responded to quickly. In a process where the liquid level is changing dynamically, such as in a continuous - flow reactor or a filling operation, the fast reaction time of the FMI51 allows for timely control actions. This helps in maintaining the stability and efficiency of the industrial process.SpecificationAccuracy±0.5% of measured value (±0.2% optional)Flow Range0.1 – 12 m/s (depends on pipe size)Pressure RatingUp to PN40 (depending on model)Temperature Range-25°C to +180°C (with PFA lining)Protection ClassIP67 / IP68 (submersible)Output Signals4-20mA, HART, PROFIBUS PA/DP, Pulse, Modbus RTUElectrodesDetect induced voltage (stainless steel, Hastelloy, titanium, or ceramic)CoilsGenerate a stable magnetic field.Company ProfileKeRui (Weifang) Automation Equipment Co.
