Abstract

Liquid metals possess significant application value in key sectors such as new energy, nuclear energy, and metallurgy due to their excellent fluidity, high electrical and thermal conductivity, and remarkable high-temperature stability. Accurate flow measurement during their application is crucial for ensuring system safety. However, conventional flow measurement techniques struggle to guarantee long-term stability under high-temperature conditions. To address this challenge, this paper proposes a non-contact alternating current excitation electromagnetic flowmeter. The design generates a stable alternating magnetic field via an excitation coil and employs externally mounted, differentially connected induction coils as the sensing element. This configuration enables non-contact measurement of liquid metal flow within metal pipes, fundamentally overcoming the reliability degradation issues associated with direct sensor contact with the measured medium. Experimental results demonstrate that the system has the potential to operate stably at a high temperature of 600°C and has achieved a high measurement accuracy of 3%.
