FIELD: measuring equipment.
SUBSTANCE: invention relates to measurement equipment and can be used for measurement of air speed and flow rate in brake pneumatic pipelines of railroad (rail) compositions, and can be used in any pipeline main lines. Technical result is achieved due to use of multiple re-reflection of probing signal from inner surface of pipeline at creation of original mathematical device for calculation of flow rate.
EFFECT: high measurement accuracy while minimizing hardware costs.
