Electromagnetic flowmeter for liquid-metal fuel assemblies

The electromagnetic flowmeter for liquid metal in fuel assemblies is considered. The device represents a magnetic system with alternating polarity. A number of poles is selected to be equal to the number of fuel elements adjoining the rod in which the flowmeter is installed. Using such flowmeter allows measuring the flowrate through each cell of fuel assemblies. Such device enables measuring the flow rate in a pipe in case of nonaxial-symmetric velocity profile. An analytical expression is given for potential distribution in the round pipe for the said device
