Abstract
A method and apparatus for dynamic calibration of monitoring equipment of the type which uses a Type-S pitot tube connected to at least one transducer utilize a calibration air conduit having a distal end positioned opposite one opening of the Type-S pitot tube and a proximate end. A blower connected to the proximate end of the calibration air conduit blows air past the standard pitot tube and at least one opening of the type S pitot tube. A standard pitot tube placed in the calibration air conduit. Differential pressure readings are taken. There is a relationship between the differential pressure reading of the standard pitot tube and the differential pressure reading of the Type-S pitot tube which does not change unless the monitoring equipment of which the Type-S is a part leaks, is plugged or is otherwise operating improperly.
