METHOD FOR MEASUREMENT OF FLOW RATE OF FLUID FLOW

摘要

Method for measurement of flow rate of fluid flow in pipeline includes measurement of time of propagation of ultrasonic acoustic signals along and across fluid flow, determination of velocity of fluid flow in planes of measurement along acoustic channels with following calculation of flow rate of fluid flow. Determination of velocity of fluid flow is carried out in two measuring planes that surround special chosen plane and for determination of value of flow rate one uses interpolation of results of measurement to special chosen plane.
