Molten Level Tracking: High-Temperature Measurement Solutions for Molten Salt Systems
2026-08-21
Accurate and stable molten level tracking is the core guarantee for the safe and efficient operation of molten salt systems, widely applied in concentrated solar power (CSP) thermal storage, salt bath heat treatment, and industrial heat transfer loops. Operating at 290°C to 600°C, molten salt features high temperature, strong corrosion, and easy crystallization, making conventional contact level measurement instruments prone to failure, data deviation and equipment downtime.
Non-contact radar level gauges have become the optimal solution for reliable molten level tracking in harsh molten salt environments. Different configurations are adopted for hot and cold salt tanks to adapt to diverse working conditions. For 565°C high-temperature hot salt tanks, waveguide radar antennas with nitrogen purge connections are essential. Continuous nitrogen purification effectively eliminates salt vapor condensation and antenna crystallization, avoiding signal blockage and ensuring long-term stable monitoring. For 290°C cold salt tanks, cost-effective PTFE horn radar antennas can meet daily operation demands.
Material selection determines the service life and accuracy of molten level tracking equipment. Wetted parts are preferably made of Hastelloy C276, which delivers excellent corrosion resistance to common solar salt and Hitec salt. 316L stainless steel with PTFE coating is a cost-effective alternative for low-temperature working conditions. Standard radar gauges for molten salt support a 0–30m measurement range, ±2mm high precision, and 4–20mA HART/Modbus RTU output, fully matching industrial monitoring requirements.
Professional installation and standardized configuration effectively reduce common operational faults. Thermal isolation structures prevent electronic components from high-temperature damage, while explosion-proof certification such as ATEX II 1/2G Ex d IIC T6 ensures safe operation in hazardous areas. For engineering procurement, key indicators including temperature resistance, material compatibility, anti-crystallization purge design and safety certifications must be verified.
In conclusion, specialized radar level gauges tailored for high-temperature molten salt environments solve the pain points of traditional molten level tracking. With optimized material selection, anti-crystallization protection and high-precision design, the equipment ensures continuous, accurate and reliable liquid level monitoring, providing solid technical support for the stable operation of CSP energy storage and industrial molten salt process systems.
