Abstract
A device (10) for measuring the flow rate of a fluid flowing in a pipe, especially for a transaction between a hydrocarbon supplier and a hydrocarbon purchaser is provided. The device (10) has a cylindrical body (11) to be interposed between two sections of the pipe. Ultrasound-beam transducers (15) are mounted on the main body (11) and intended to measure at least a rate of movement of the fluid stream as this flows through the device (10). At least one converter converts the signals emitted by the transducers into a flow rate signal. The transducers (15) are mounted and uniformly distributed on two coaxial parallel rings (12, 13). The transducers (15) of a first ring (12) are angularly offset relative to the transducers of the second ring (13).
