Intelligent microwave level gauges (radar) – These intelligent transmitters, which are used for continuous and non-contact precise level measurement, have been certified by NMI and PTB and are suitable for use in situations requiring accurate measurement and volume control. Features and advantages: · Precision of 0.5 MM (2-level detection) · International certifications (NMI, PTB), making them suitable for use in measurement-related applications. ·Perform on-site operations easily through the numeric display menu. ·Configuration, document preparation, and maintenance are carried out through the operation software. ·A dedicated antenna can be selected. ·It offers good cost-performance and can be easily installed using a four-wire cable with a 24V DC power supply (intrinsically safe). ·All antennas are connected using a hermetic process. ·The total volume control accuracy is 3 mm. When using MicropilotS, it can be applied in storage tanks as well as for measurement and transfer purposes, enabling high-precision level measurement. Applied in relevant scenarios in accordance with OIMLR85 and API3.1B. ·The FMR533 with a parabolic antenna is highly suitable for measurements inside tanks, with a range of up to 40M. The FMR532 with a planar antenna is appropriate for measurements inside waveguides, with a range of up to 38M. The FMR531 with a rod antenna can be used for high-precision measurements in highly corrosive media as well as in narrow installation ducts. ·The FMR530 with a horn antenna is suitable for use inside tanks, in situations where the use of parabolic antennas is not possible due to the geometric constraints of the storage tank and the mounting ducts. Function and System Design, Measurement Principle: MicroPilot is a \"top-down\" time-of-flight measurement system. Used to measure the distance from the reference point (i.e., the process connection point) to the surface of the material. The antenna emits microwave pulses, which are reflected off the surface of the material being tested and then detected by the radar system. The antenna receives the reflected microwave pulses and transmits them to the electronic circuitry; the microprocessor processes these signals to identify the echoes generated by the microwave pulses on the surface of the material. Accurate signal identification is carried out by the Pulse Master software, which incorporates years of experience in time-of-flight measurement. Millimeter-level precision can be achieved through the software’s patented algorithm. The distance D from the surface of the material is proportional to the time duration t of the pulse: D = c·t/2, where c is the speed of light. Since the distance E from the empty tank is known, the material level L can be calculated as follows: L = E – D. The reference point for E can be seen in the diagram above. MicroPilot has echo interference suppression functionality. This function can be activated by the user, ensuring that interference echoes caused by sources such as edges and welds are not mistaken for material echoes. The output of MicroPilot is set by entering the height of an empty tank E (equal to zero), the height of a full tank F (equal to the full scale), as well as some application parameters. The application parameters will automatically adjust the instrument to the measurement environment. For current-output instruments, data points “E” and “F” correspond to 4mA and 20mA outputs respectively, while for digital-output instruments and display modules, they correspond to 0% and 100% respectively. Linearization can be performed on-site or remotely, manually or semi-automatically by entering forms, in order to measure the level of liquid in spherical tanks, horizontal cylindrical tanks, and cones with conical bottoms. The Micropilot S device structure can be used for measurements inside tanks or waveguides. Different models of instruments are suitable for various applications: The Micro Pilot SFMR532, equipped with a planar antenna, is better suited for use in waveguides with a diameter of ≥150 mm. The Micro Pilot SFMR530, with a horn antenna, can be used in waveguides with a diameter of <150 mm; however, it cannot be used in applications involving volume measurement. The Micro Pilot SFMR533, featuring a parabolic antenna, is more appropriate for measurements inside tanks. The Micro Pilot SFMR530, with a horn antenna, can be used for measurements in installation ducts with smaller diameters. The Micro Pilot SFMR531, equipped with a PTFE rod antenna, is better suited for use in environments containing highly corrosive media (such as sulfur). All of these instruments come equipped with a passive 4-20 mA output that supports the HART protocol. They can be operated using the display and control module VU 331, or via a personal computer, FXAl93, and the ToF Tool operating software. ToF Tool is a graphical operation software developed by Endress+Hauser specifically for time-of-flight-based instruments such as radars, ultrasonic sensors, and guided-wave radars. Its functions include configuration, data encryption, fault diagnosis, and the creation of files for measurement points.
