Abstract
A differential static pressure measuring or activating device measuring fluid flow through a duct including two pitot tubes each including a proximal end connected to a valve, a distal end portion located in the duct extending generally parallel to each other and perpendicular to the air flow through the duct having open distal ends and a plate located between the distal end portions of the tubes creating a differential static pressure between the open ends of the tubes. The open distal ends of the tubes incline toward the plate such that the open ends face toward and away from the direction of the gas flow through the duct.
