Sensor manifold for a flow sensing venturi

摘要

A flow sensing venturi system 10 includes a venturi body 16 and a manifold 18 mounted thereto. The manifold 18 is thermally isolated from the venturi body 16. A multiple of sensor ports 24 are formed into the manifold 18 which support each individual sensor 20 and provide communication between the sensor 20 and one or more passageways 26L,26H. The passageways communicate with a single high-pressure 32 and a single low-pressure 36 sense line. The high and low pressure sense line 32,36 tap respective high and low pressure areas within the venturi body 16. The sensor 20 is individually screwed into the manifold 18 to provide an airtight connection for two independent sensor input ports 44,46. Replacement of individual sensors 20 is thereby greatly simplified.
