Device for Checking a Flow Pressure Measurement Probe, and Probe Comprising the Device
First Claim
1. A device for checking a flow pressure measurement probe, the probe having an internal volume and at least one orifice for communication with the outside of the volume, comprising:
- an acoustic transmitter and an acoustic receiver configured to be connected to the internal volume so that the transmitter transmits an acoustic signal that propagates in the internal volume and so that the receiver picks up an acoustic signal observed in the internal volume; and
means for comparing the acoustic signal observed in the internal volume with a reference acoustic signal,wherein the connection of the acoustic transmitter and the acoustic receiver to the internal volume is made temporarily.

Abstract
A device is provided for checking a flow pressure measurement probe as well as a probe comprising the device. The probe includes an internal volume and at least one orifice for communication with the outside of the volume. The device includes: an acoustic transmitter and an acoustic receiver that are intended to be connected to the internal volume so that the transmitter transmits an acoustic signal that propagates in the internal volume and so that the receiver picks up an observed acoustic signal; and, means for comparing the observed signal with a reference signal. The device may be a stand-alone device or may be integrated into the probe.
