Design of a magnetic flowmeter for conductive fluids

The operation of a magnetic flowmeter for conductive fluids is analyzed and the magnetic, and electric fields in it are described as solutions of boundary value problems. Finite-element methods are utilized to solve the problems, and solutions are presented for a variety of flow profiles and inner tube conductivities. The method gives an insight into both the phenomenon involved and the effects of the geometry and the material characteristics on the accuracy and sensitivity of the flowmeter.<
