FIELD: gas dynamics.
SUBSTANCE: device has extension equipped with flow direction finder, which finder is connected with unit for correction of position of extension relatively direction of flow, digital conversion and analog signals registration unit, unit for measuring of derived speed of flow and for visualization of results of processing. Static pressure pulsation detector and total pressure pulsation detector are placed in extension. The detectors are mounted in parallel and in perpendicular to direction of flow to provide measurement at the same preset point. Device provides simultaneous digital registration of analog signals at high frequency (1 MHz) and subsequent processing of signals to determine pulsations of derived speed of flow.
EFFECT: improved precision of measurements in wider frequency range.
