<p>A process control instrument (10) adapted to provide an output indicative of a parameter of a process fluid is disclosed. The process control instrument is designed to be attachable to a flange (13) having a first passageway (24) filled with process fluid. A body (14) of the process control instrument has an opening (28) adjacent to the first passageway (24) adapted to receive process fluid from the first passageway. A seal (48) positioned in the opening (28) and attached to the body (14) at a seal outer diameter is adapted to prevent process fluid from leaking from the first passageway (24) and the opening (28) past the flange (13).</p> |
