ABSTRACT:
A flangeless electromagnetic flowmeter insertable between upstream and downstream pipes which have the same internal diameter, the adjacent ends of said pipes having like flanges. The cylindrical body of the flowmeter is interposed between the flanged ends of the pipes, the body being provided with an annular pressure vessel formed of insulating material to define a central flow passage whose diameter matches the internal diameter of the pipe whereby the flowmeter functions to meter the flow rate of fluid passing through the pipes and the passage along a longitudinal axis extending therethrough. A pair of electromagnetic coils is embedded in the vessel at opposed positions with respect to the passage to establish a magnetic field therein whose lines of flux are substantially perpendicular to the longitudinal axis. Also embedded in the vessel is a pair of electrodes at opposed positions with respect to the passage, the electrodes lying along a transverse axis at right angles both to the lines of flux and the longitudinal axis. The flanged ends of the pipe are bridged by bolts to clamp the flowmeter body therebetween.
