Patent ID: 7228748

Claim:
An electromagnetic flow meter apparatus comprising: an elongate section of flow conduit through which fluid can flow along a flow path, the flow conduit having a generally circular flow conduit cross-section in a direction transverse to said flow path; an elongate molded insert positioned within and extending along said section of flow conduit, the insert comprising the following integrally molded components: an inlet arranged to receive fluid flowing along said flow conduit the inlet having a generally circular cross-sectional shape in a direction transverse to a longitudinal axis of the insert and having cross-sectional dimensions similar to cross-sectional dimensions of the flow conduit into which the insert is adapted to be inserted; an outlet configured to output fluid having flowed through said insert into said section of flow conduit, the outlet having a generally circular cross-sectional shape in a direction transverse to the longitudinal axis of the insert and having similar dimensions to those of the flow conduit into which the insert is adapted to be inserted; and a measuring section positioned between said inlet and outlet, said measuring section having an inner surface which defines a measuring channel through which fluid from said inlet can flow and wherein said measuring channel has a cross-section in a direction transverse to said flow path which has more than four sides and which is different from said flow conduit cross-section.
