Abstract
In an aspect, an electromagnetic flow meter assembly includes a flow tube housing having a flow inlet and a flow outlet at opposing ends of a fluid passageway running through the flow tube housing and further having an electrode receptacle defining a cavity opening into the fluid passageway. The flow meter assembly also includes an electrode positioned within the electrode receptacle and having a sensing end surrounded by a porous plug fitted within the cavity, said porous plug providing wetted exposure of the sensing end of the electrode when the fluid passageway is filled with fluid. The flow meter assembly further includes one or more channels configured to vent entrained gas from around the porous plug when the porous plug is fitted within the cavity and the fluid passageway is filled with fluid.
