Beschreibung
Zusammenfassung:	FIELD: physics. ^ SUBSTANCE: measuring body with streamlined aerodynamic cross-cut is placed inside main pipeline across the flow, so that the angle between flow speed vector W and lateral axis linking two reference points of measurement body was equal to the angle between flow speed vector V and calibration lateral axis. At least three pairs of drain holes along the measurement body in vicinity of ground cut assist in measuring local values of frequency and amplitude of pressure variation caused by torrents induced by the measurement body. These torrents are used to define local flow speed and density distribution. All variants of the device are supplied with sensors of temperature, static and absolute pressure and total-pressure tube. ^ EFFECT: increased flow measurement accuracy and reliability, and implementation of measurement in stratificated gas or liquid flows. ^ 25 cl, 26 dwg
