Abstract
1. Способ измерения расхода жидкости, протекающей через канал, заключающийся в том, что в сечении канала выбирают сложную виртуальную измерительную поверхность, перекрывающую полностью все сечение канала, затем в ее геометрическом центре или центрах устанавливают ультразвуковой источник или источники, формирующие группу узконаправленных лучей, пронизывающих виртуальную измерительную произвольную поверхность с заданным шагом по широте и долготе так, что она покрывается сеткой точек пересечения каждого луча с виртуальной измерительной поверхностью, причем каждый луч перпендикулярен поверхности в точке пересечения, затем для каждого луча проводят измерение скорости потока вдоль луча в точке пересечения с виртуальной измерительной поверхностью в направлении нормали к упомянутой поверхности по доплеровскому смещению частоты эхосигнала от точки пространства на виртуальной измерительной поверхности, после чего проводят интегрирование по всем точкам сетки.2. Способ по п.1, отличающийся тем, что сложной виртуальной измерительной поверхностью является виртуальная сфера, а единственной точкой установки одного многолучевого ультразвукового источника является геометрический центр этой сферы.1. A method of measuring the flow rate of a fluid flowing through a channel, namely, that a complex virtual measuring surface is selected in the channel section that covers the entire channel section, then an ultrasonic source or sources are installed in its geometric center or centers, forming a group of narrowly directed rays penetrating a virtual measuring arbitrary surface with a given step in latitude and longitude so that it is covered by a grid of points of intersection of each beam with a virtual measuring surface, and each beam is perpendicular to the surface at the point of intersection, then for each beam, the flow velocity is measured along the beam at the point of intersection with the virtual measuring surface in the direction normal to the surface by the Doppler shift of the frequency of the echo signal from the point of space on the virtual measuring surface, and then Integrate over all grid points. 2. The method according to claim 1, characterized in that the complex virtual measuring surface is a virtual sphere, and the only installation point of one multi-beam ultrasonic source is the geometric center of this sphere.
