随着微处理器的广泛应用,超声流量计的性能已有了重大的提高。本文介绍了把声束透射型和多普勒型的优点结合在一个夹装式流量计中的新颖设计。它利用宽声束发射原理,使流量计对管道材质的声速变化不敏感。
With the extensive use of microprocessors, ultrasonic flowmeter performance has been greatly improved. This article presents a novel design that combines the benefits of beam-transmissive and Doppler modes in an in-line meter. It uses the principle of wide beam emission, the flow meter on the pipe material is not sensitive to changes in the speed of sound.
