Static air sampling
Webstatic sampling means a measurement of total accumulated mass uptake of a pollutant in ambient air using a container for gravitational settling of particulate matter, or a cylinder … WebBy static probes inserted in the process stream. By small openings located on the pitot tube itself or on a separate aerodynamic element. Wall taps can measure static pressures at flow velocities up to 200 ft/sec. A static probe (resembling an L-shaped pitot tube) can have four holes of 0.04 inches in diameter, spaced 90o apart.
