A pressure measuring system is described for use in obtaining in-flight wing profile drag measurements for low values of dynamic pressure and Reynolds number. The system is supported by a wing in flight which has a total pressure head arranged in spaced relation with a wake (as the wake is generated by the wing), and a reference static pressure head adapted to be displayed along an accurate path through the wake. A total pressure port and a static pressure port are included. A differential transducer is connected to the heads through a pressure switching device provided to selectively connect the heads to the transducer in opposed relation. Thus, a single differential transducer is adapted to be utilized in obtaining differential pressure measurements for the wake.
