Abstract

A magnetic flowmeter which generates a signal proportional to the flow rate of a fluid passing through a pipe to intersect a magnetic field whose lines of flux are substantially parallel to a transverse axis normal to the longitudinal axis of the pipe. The flowmeter includes two electrode assemblies mounted on the pipe on opposite sides of the transverse axis and capacitively coupled to the fluid. The effective coupling capacity of the electrodes in each assembly is such as to render the signal substantially immune to the influence of non-axisymmetric flow profiles.
