Device for measuring the total pressure of a flow and method implementing the device

Abstract

The invention relates to a device and to a method for measuring the total pressure of a flow. According to the invention, the device comprises a Pitot tube (25), means for measuring the total pressure at a stagnation point (4, 12) and comparison means (32, 33) for comparing pressures measured by the Pitot tube (25) and the means for measuring total pressure at the stagnation point (4, 12), the Pitot tube (25) and the means for measuring total pressure at the stagnation point (4, 12) being joined together and tapping air streams off the flow along the same axis (7). The method implementing the device includes comparing the measured pressures and if the difference between the two measured pressures is greater than a given discrepancy, then a warning is generated specifying that only the higher pressure has a good likelihood of being correct.
