This application discloses an online monitoring system for molten salt parameters, relating to the field of intelligent monitoring and diagnostic technology. The online monitoring system selects a first pipe with a curvature less than a preset threshold as the measurement segment in a concentrated solar power (CSP) plant, and installs pressure testing devices at both ends, constructing an online measurement structure based on the pressure difference principle. This system achieves real-time, in-situ monitoring of molten salt viscosity, overcoming the problems of poor timeliness and inability to reflect real-time operating status in traditional offline sampling and analysis. The limitation on pipe curvature ensures the stability of fluid flow, allowing the measured pressure difference to accurately reflect the viscous resistance of the molten salt. This solution has a compact structure, is easy to deploy in engineering, and provides stable and reliable technical support for real-time perception of the molten salt status, operational risk assessment, and early warning decision-making in CSP plants.
