Abstract
A magnetic flowmeter includes a flow tube that is connected in fluid-conducting relation between a pair of axially spaced sections of a conduit, a first electrical connector being fixed to the outer surface of the flow tube and including first terminals electrically connected with spaced internal electrodes, respectively, that contact the fluid flowing through the tube. A second electrical connector is provided for separable connection with the first connector, which second connector includes an end-fire electromagnet for establishing a transverse magnetic field in the flow tube via the first connector, and second terminals for connecting the electrodes with a flow-indicating meter via the first terminals, respectively, and a cable. In order to calibrate the meter for use with a plurality of flow tubes having different internal cross-sectional dimensions, respectively, the first and second connectors are provided with cooperating size coding and decoding devices, respectively.
