Abstract
An electromagnetic flowmeter capable of measuring fluids having any degree of conductivity, including fluids having dielectric properties. The fluid to be measured is fed through a dielectrically-lined flow tube to intersect a transverse magnetic field, thereby inducing a voltage in a pair of planar detecting electrodes disposed within the dielectric lining. Each detecting electrode and an associated planar shielding electrode are unitized in an assembly wherein the electrodes are embedded in a liner segment formed of rigid dielectric material, connections to the electrodes being made by means of a coaxial line extending radially through an opening in the flow tube, the line having an outer conductor attached to the shielding electrode and an inner conductor attached to the detector electrode, the space between the line conductors being filled with the same dielectric material as that of the segment.
