ABSTRACT:
Electrodes for an electromagnetic flow meter are mounted through a pipe wall using pairs of concentric electrodes electrically insulated from each other and from the mounting pipeline while electrically contacting a fluid in the pipeline being measured for flow rate. The electrode pairs are held on the pipeline wall on a line intersecting the fluid flow at a right angle and are electrically connected to supply signals induced by the fluid flow to a measuring circuit. The concentric electrode structure provides two electrode pairs at each electrode site on the pipeline wall.
