FIELD: the invention refers to measuring technique and designed for measuring speed of instantaneous or integral consumption of liquid(of oil and products of its processing) in completely filled(pressure) pipelines.
SUBSTANCE: the arrangement includes in itself a part of a tube in which along generating line at given distance R relatively to each other there are two hollow openings whose axles are perpendicular to the axle of the tube. Into the openings receiving-transmitting electric acoustic transformers are mounted. They are installed so that the centers of their radiating plates are on the same level with the inner surface of the tube. The radiating surface of each of the indicated transformers is located under an angle 300 -600 to its longitudinal axle that provides acoustic communications along three chords. The distance R is chosen according to the cited formula.
EFFECT: the arrangement has a simple construction and provides improved correlation signal/noise in the measuring signal.
