Apparatus and method for ultrasonic measurement of fluid flow rate and flow

There is provided a device for measuring a flow rate and a flow rate of a fluid passing in a main flow direction, the device comprising: a housing; means for separating the fluid stream into a plurality of streams, each of the plurality of streams passing through a channel for which 5 is assigned and which is located in the housing; a pair of ultrasonic transducers located in the housing, intended to form and receive ultrasonic waves passing through the channel and to generate electrical signals; means for guiding ultrasonic waves along an acoustic path, the acoustic path passing through the channel; and means for calculating the flow rate and flow rate of the fluid using the generated electrical signals. The invention further provides a method for using the equipment 10 for measuring the flow speed and the flow rate of the fluid. 提供了用于测量在流动主方向上通过的流体的流速和流量的设备，该设备包括：壳体；用于将流体流分离成多个流的装置，多个流中的每一个在为它分配5的并且位于壳体中的通道中通过；一对超声换能器，该一对超声换能器位于壳体中，旨在用于形成和接收穿过通道的超声波以及生成电信号；用于沿着声学路径引导超声波的装置，该声学路径穿过通道；用于使用生成的电信号来计算流体流速和流量的装置。
