Patent ID: 7437952

Claim:
A shrouded flow meter comprising: a fluid tight inner conduit operable to conduct a fluid therethrough, said inner conduit having an inlet and an outlet with respective inlet and outlet fittings; a fluid tight outer conduit disposed over said inner conduit with a space therebetween, said outer conduit having an inlet and an outlet with respective inlet and outlet fittings; and a detector attached to said outer conduit and extending from an exterior of said outer conduit, said detector operable to sense a signal indicative of a characteristic of a fluid in said inner conduit, said detector being isolated from direct contact with the fluid flowing through said inner conduit, and said detector being external to said interior of said inner conduit, wherein said inlet and outlet fittings of said inner conduit couple in a fluid-tight manner with end fittings of an inner conduit in other shrouded apparatuses, said inlet and outlet fittings of said outer conduit couple in a fluid tight manner with end fittings of an outer conduit in said other shrouded apparatuses, and said fluid-tight coupling of said inlet and outlet fittings of said inner conduit is independent of said fluid-tight coupling of said inlet and outlet fittings of said outer conduit.
