Single-magnet rotary flowmeter for liquid metals


Single-magnet rotary flowmeter for liquid metals

Priede, J.; Buchenau, D.; Gerbeth, G.

We present a novel design of a contactless flowmeter using a single cylindrical permanent magnet magnetized perpendicularly to its axis, about which it can freely rotate, and placed close to a duct with a liquid metal flow. The electromagnetic torque on the magnet caused by the liquid metal flow sets the magnet into rotation.
The equilibrium rotation rate, which is attained at a vanishing net electromagnetic torque on the magnet, depends only on the flow rate and the geometry of the system while it is independent of the electromagnetic torque itself.
A laboratory model of such a flowmeter has been built and tested on a liquid metal flow.
