摘要： The measurement of volume flows or mass flows in the intake system of motor vehicle internal combustion engines plays a significant role in reducing pollutant emissions. Therefore, an ultrasonic flow meter for measuring a flow rate of a fluid flowing in a primary flow direction is described. The ultrasonic flow meter has at least two ultrasonic transducers, the ultrasonic transducers being capable of emitting and/or receiving ultrasonic waves at an angle α to the primary flow direction which is different from 90°. Furthermore, the ultrasonic flow meter has at least one guide element which is entirely or partially situated in the fluid. This guide element diverts at least one part of the flowing fluid in such a way that in the diversion, a velocity component is transferred to at least one part of the flowing fluid perpendicular to the primary flow direction. Guide vanes or displacers in particular are described as guide elements. In addition, turbulators may be provided on the guide elements, the turbulators generating a longitudinal fluid bed along the guide elements and thus causing the flow of the fluid to have a better contact with the guide elements when flowing around them. This reduces turbulences within the ultrasonic flow meter. Compared to the devices known from the related art, the ultrasonic flow meters described are distinguished by an improved signal-to-noise ratio and accordingly by a higher measuring precision.

摘要： Measuring volume flows or mass flows in the intake system of motor vehicle internal combustion engines plays an important role in reducing harmful emissions. Therefore, an ultrasonic flow meter for measuring a flow velocity of a fluid flowing in an essentially laminar flow in the main flow direction is described. The ultrasonic flow meter has at least two ultrasonic transducers, the ultrasonic transducers being able to emit and/or receive ultrasonic waves at an angle α to the main flow direction which is different from 90°. Furthermore, the ultrasonic flow meter has at least one turbulator situated upstream from at least one ultrasonic transducer in the main flow direction of the fluid, which generates longitudinal eddies in at least one zone adjacent to the at least one ultrasonic transducer, in particular in a protrusion in a wall of a flow pipe and thus improves the flow of the fluid in this zone in the flow pipe. Wedge-shaped turbulators protruding into the flow of the fluid or flow grooves are provided in particular as turbulators. The ultrasonic flow meter is distinguished, in comparison with devices known from the related art, by improved signal-to-noise ratio and thus by higher measurement accuracy.
