Abstract
Apparatus for permanent installation in a heating or air conditioning duct to sense total and static pressure of air flowing therethrough. A plurality of manifolds are arranged within the duct to sense total pressure at a number of selected locations in a transverse plane of the duct. The plurality of manifolds communicates with a connecting manifold either directly or through sensing tubes arranged axially within the manifold tubes. Static pressure is also sensed at a plurality of preselected locations in the duct and communicated to at least one additional manifold tube arranged within the duct. Total and static pressure are communicated through single openings in the duct well for attachment exteriorly thereof to an appropriate measuring instrument.
