  • High pressure magnetic flowmeter with stress resistant electrode assembly
    Patent number: 7938020
    Abstract: An electrode assembly comprises a housing, an electrode, a retainer and a potting material. The housing has a first end and a second end, with the electrode extending from the first end of the housing to a process flow. The retainer is positioned about the electrode, inside the housing. The potting material fills voids between the first end of the housing and the second end of the housing, such that the potting material limits displacement of the electrode when the electrode head is subject to pressure from the process flow.

  • Gasket arrangement for sanitary process flow meter
    Publication number: 20060070437
    Abstract: A flow meter assembly includes a flow meter for use in a sanitary process environment. The flow meter includes a flow tube having an end which includes a first gasket lip and a first abutting face. A sealing flange mates with the flow tube and includes a second gasket lip and a second abutting face configured to abut against the first abutting face. A gasket provides a seal between the first and second gasket lips. The first abutting face and second abutting face limit compression of the sealing flange.
