Sensor manifold for a flow sensing venturi

摘要

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