ABSTRACT:
The present invention entails a transverse type pressure averaging primary device that is designed to be mounted within a duct and designed to sense both total and static pressures of fluid flow passing within the duct. More particularly, the pressure averaging primary system of the present invention includes high and low pressure lines that extend transversely across the duct and which generally includes multiple pressure sensing points along the lines for sensing both total and static pressure. In the case of the high pressure line, the respective total pressure sensing points thereof are appropriately confined within cylindrical shrouds. Selected cylindrical shrouds include extensions that extend to and are secured to the low or static pressure line for structurally integrating and reinforcing the spans of the high and low pressure lines.
