Abstract
The present invention entails a branch averaging pitot system for sensing differential pressure within a system of air or gas and providing a differential flow signal to a flow transmitter forming a part of the air monitoring system of the present invention. The branch averaging pitots include an array of shrouded total pressure pitots strategically spaced about the cross sectional area of an air receiving duct assembly and down stream from a honeycomb type air flow straightening section. In addition, an array of static pressure pitots are also provided, and wherein the respective static and total pressure pitots are communicatively connected by separate manifolds internally within the air receiving duct assembly. Openings in the pitots are relatively small (0.030 inches to 0.060 inches), and said transmitter is adapted to continuously direct a flow of purging air therefrom back to and through the pitots in order to keep them open at all times.
