Our high temperature high pressure radar level meter (Model SLDL5228) is a 26GHz non-contact level measurement solution engineered to deliver uncompromising accuracy and reliability in the harshest industrial environments. This high temperature high pressure radar level meter is designed to withstand extreme temperatures, high pressures, and corrosive conditions, making it the ideal choice for demanding applications across oil & gas, chemical processing, and power generation.
The high temperature high pressure radar level meter emits 26GHz microwave pulses that travel at the speed of light toward the surface of the measured medium. A portion of the pulse energy is reflected back to the instrument’s antenna, and the time-of-flight between transmission and reception is used to calculate the exact distance to the medium surface, delivering precise, real-time level data. This non-contact technology ensures the high temperature high pressure radar level meter operates reliably without direct contact with the process medium, eliminating wear and contamination risks.

The high temperature high pressure radar level meter is built to perform in the most extreme thermal and pressure conditions. With a standard process temperature range of -50°C to 200°C, and up to 800°C with isolation accessories, this high temperature high pressure radar level meter is perfect for high-temperature applications like boiler steam drums, coking plants, and high-temperature reactors. It also supports process pressures up to 20 bar standard, and 400 bar with isolation, making it suitable for high-pressure vessels and pipelines.
With a maximum measuring range of 80m and a measurement deviation of just ±2mm, the high temperature high pressure radar level meter delivers industry-leading accuracy for both liquid and solid level measurement. The 26GHz frequency and multiple beam angle options (10°, 8°, 6°) ensure the high temperature high pressure radar level meter can penetrate dust, steam, and foam, maintaining reliable measurement even in challenging process conditions.
The high temperature high pressure radar level meter features 304/316L stainless steel antennas, ensuring corrosion resistance and long service life in harsh chemical environments. It supports multiple process connections (thread G1A, flange) and flexible installation options, including short nozzles and extension tubes, making it easy to integrate into existing process systems.
The high temperature high pressure radar level meter supports a full range of industrial communication protocols, including 4-20mA/HART, Profibus PA, Modbus, and Bluetooth, enabling seamless integration with DCS and SCADA systems. It is also certified to ATEX, IEC, CSA, and SIL2 standards, ensuring the high temperature high pressure radar level meter meets global safety requirements for hazardous industrial environments.
This high temperature high pressure radar level meter is ideal for a wide range of extreme industrial applications, including:
•Oil & gas refineries and petrochemical plants
• Boiler feed water and steam drum level measurement
• High-temperature chemical reactors and coking plants
• High-pressure storage tanks and process vessels
• Power generation and steel manufacturing
For optimal performance of the high temperature high pressure radar level meter, follow these key installation rules:
1.Install the high temperature high pressure radar level meter at least 200mm away from the vessel wall to avoid interference.
2. Ensure the antenna is installed perpendicular to the medium surface to maintain maximum measuring range.
3. For conical vessels, install the high temperature high pressure radar level meter at the center of the tank roof to ensure full-range measurement to the vessel bottom.
4. When installing in a short nozzle, ensure the antenna extends at least 10mm beyond the nozzle end to avoid false echoes.


The high temperature high pressure radar level meter (SLDL5228) is the ultimate solution for reliable, accurate level measurement in extreme industrial conditions. With its 80m range, ±2mm accuracy, 800°C temperature resistance, and global safety certifications, this high temperature high pressure radar level meter delivers unmatched performance and value for demanding industrial applications.
