The E+H FMI51 Level Transmitter, a product of the renowned Endress+Hauser, is a highly sophisticated and reliable instrument designed for continuous level measurement of liquids across a wide array of industries. Leveraging advanced capacitive measuring principles, the FMI51 has established itself as a go - to solution for applications where precision, durability, and adaptability are of utmost importance.
At its core, the FMI51 utilizes the capacitive measuring principle. A capacitive sensor consists of two or more conductors separated by an insulating material (dielectric). In the case of the FMI51, the probe acts as one of the conductors, and the process medium or the vessel wall (depending on the installation and medium characteristics) can act as the other. When the level of the liquid in the vessel changes, the dielectric constant between the probe and the reference conductor changes proportionally. The FMI51 measures this change in capacitance, which is then correlated to the liquid level.
For example, if the liquid has a higher dielectric constant than the air above it, as the liquid level rises and more of the probe is immersed in the liquid, the overall capacitance of the sensor increases. This change in capacitance is detected by the transmitter's electronics, and through complex algorithms, it is converted into an accurate level measurement.

This capacitive measuring approach offers several distinct advantages. Firstly, it allows for highly accurate measurements even in challenging environments. The FMI51 can achieve high precision in determining liquid levels, with minimal interference from factors such as temperature fluctuations, pressure variations, and the presence of foam or vapor above the liquid surface.
Secondly, it has a wide range of applications. The FMI51 can be used with various types of liquids, including those with high conductivity. In fact, for media with a conductivity of 100 μS/cm and higher, no adjustment is necessary. The probes are pre - adjusted to the ordered probe length at the factory, covering the range from 0% to 100% of the measuring span. This factory calibration simplifies and speeds up the commissioning process significantly, reducing installation time and costs.
Product Overview
The probe of the FMI51 is a key component in its design. It is a fully insulated rod probe, which is crucial for its performance in different process conditions. The insulation material is carefully selected to withstand harsh environments, including extreme temperatures and pressures.
The rod probe comes in different materials, such as 316L stainless steel, which provides excellent corrosion resistance. In addition, for applications where contact with food or pharmaceutical products is involved, the probe materials are FDA - listed, ensuring compliance with strict hygiene and safety standards. The probe can be customized in terms of length, with active probe lengths available to suit the specific requirements of the application. For example, active probe lengths can range from a few centimeters to several meters, allowing for accurate measurement in vessels of different sizes.
The FMI51 offers multiple housing options to meet diverse installation and environmental needs. One common housing option is made of aluminum. Aluminum housings are lightweight yet durable, providing good protection against dust and water. They are typically used in general industrial applications where the environmental conditions are not overly harsh. The degree of protection for these aluminum housings is often IP66 or NEMA 4X, which means they are well - protected against dust ingress and can withstand powerful water jets from any direction without causing harmful effects to the internal electronics.
For more demanding environments, such as those with high humidity, chemical exposure, or where explosion - proof requirements are strict, stainless - steel housings can be selected. Stainless - steel housings offer enhanced corrosion resistance and can meet higher explosion - protection standards. They are suitable for applications in the oil and gas industry, chemical plants, and other hazardous areas.The FMI51 is designed to be easily integrated into existing process systems, thanks to its variety of process connection options
