Device and Method for Ultrasonic Measurement of the Fluid Flow Velocity and Flowrate

Device for measuring the flow velocity and flowrate of fluid passing in the flow main direction containing the casing, the means for separating the fluid flow into the plurality of flows, each of the plurality of flows being passed in the channel allocated for it located in the casing, pair of ultrasonic transducers in the casing intended for forming and receiving the ultrasonic waves crossing the channels and generating the electric signals, the means for directing the ultrasonic waves along the acoustic path crossing the channels; means for calculating the fluid flow velocity and flowrate using generated electric signals, is offered. The method in which the abovementioned device for measuring the fluid flow velocity and flowrate is used is also offered.
