Patent

CA 2739271

The invention relates to a device for checking a flow pressure measurement probe and to a probe comprising the device. The probe (10) comprises an internal volume (14, 23, 24) and at least one orifice (20) for communication with the outside of the volume (14, 23, 24). The device comprises: .cndot. an acoustic transmitter (26) and an acoustic receiver (27) that are intended to be connected to the internal volume (14, 23, 24) so that the transmitter (26) transmits an acoustic signal that propagates in the internal volume (14, 23, 24) and so that the receiver (27) picks up an observed acoustic signal; and .cndot. means (28) for comparing the observed signal with a reference signal. The device may be a stand-alone device or may be integrated into the probe.
