VAP ® Pitot VAP3® Pitots have a unique Velocity Averaging and Parallel Plate proprietary design. When inserted into air or gas flow ducts, VAP3® Pitots provide an accurate differential pressure output that allows for precise flow measurement and control of your process. VAP3® Pitots work well with almost any transmitter and are designed for both clean air applications (VAP3®/SA) and for heavily particulate‐laden applications (VAP3®/PA‐ Plug Resistant). Both styles of VAP3® Pitots can be installed directly into ducts or can be incorporated into flow‐conditioning devices, such as the High Beta®, which are designed for installations where turbulent air and insufficient duct runs are present. Velocity Averaging Parallel Plate Design: Multi‐ ple differential pressure‐sensing ports allow velocity averaging throughout the full traverse of the duct VAP3® Pitot Arrays in Various Duct Orientations PITOT ARRAY INSERTED DIRECTLY INTO DUCTS VAP3®/PA Resists Airborne Particulate Plugging: No blast purge system is required Hardened, Slick Surface: Teflon® hard anodized 6063 aluminum extrusion with a Rockwell Hardness of 65C (for temperatures up to 700° F) Low Profile Design: Minimizes unrecovered pres
