FIELD: measuring equipment.
SUBSTANCE: disclosed are viscous fluids flow rate ultrasonic measurement device and method. In one embodiment ultrasonic flow measurement system comprises ultrasonic flow meter, flow stabilizer and tapering adapter. Ultrasonic flowmeter comprises two ultrasonic transducers, used for of ultrasonic signals exchange through fluid medium flow, passing between transducers. Flow stabilizer is located upstream of ultrasonic flow meter. Tapering adapter is arranged between flow stabilizer and ultrasonic flow meter for reduction of fluid medium flow cross section area, passing from flow stabilizer to ultrasonic flow meter. Device also contains flow rate calculating logical circuit, made with possibility of volumetric flow rate calculating through ultrasonic flowmeter using correction based on fluid medium flow profile dynamic coefficient and flow meter conversion factor, which is ratio of reference discharge volume to volume, output by ultrasonic flow meter placed over specified period of time.
EFFECT: technical result is enabling of viscous fluids flow rate measurement accuracy.
