ShareTURBINE FLOWMETER FOR LIQUID HELIUM WITH THE ROTOR MAGNETICALLY LEVITATED.
Author(s) : RIVETTI A.
Type of article: Article
Summary
THE ABSENCE OF CONTACT ENSURES A GOOD MEASUREMENT REPEATABILITY, EVEN AT VERY LOW LIQUID HELIUM FLOW RATE VALU THE ROTOR IS MAGNETICALLY SUSPENDED BY THE MEISSNER EFFECT: AT LIQUID HELIUM TEMPERATURES TWO MAGNETIC FIELDS GENERATE SUSTAINING FORCES AGAINST THE SURFACE OF THE TWO ROTOR ENDS, WHICH ARE MADE OF NIOBIUM. THE ROTOR EQUILIBRIUM IS INTRINSICALLY STABLE. A PARTICULAR CONFIGURATION OF THE SUPERCONDUCTING WINDINGS AND OF THE ROTOR ENDS ALLOW THE ROTOR TO LEVITATE AND HOLD GOOD AXIAL AND RADIAL STABILITY.
