Fixing and application of multiple route time difference type Ultrasonic flowmoter on large pressure steel tube and large box contain

通过典型例子简单的分析了多声路时差式超声波流量计在大型压力钢管及混凝土箱涵上从换能器选型、安装断面的选择、声路布置及安装方法等方面的不同点与相似点,以及简单的阐述了多声路超声波流量计的安装过程。

Through typical examples,the paper analyses the differences and similarities of the choices of transducers and measure sections,multipath layout ,installation method etc, as multipath ultrasonic transit time flowmeters are applied in pressure pipes and concrete culvert boxes. And it intrduces sinply the installation process of mu ltipath ultrasonic transit time flowmeter
