一、管道设计、口径选择涡街流量计对管道设计有较高要求(如直管道要求、同径度要求等),若管道设计不能满足涡街流量计的安装要求,其计量特性就会产生较大偏差。用户需要根据自身的用气量选择涡街流量计的口径。
First, the pipe design, caliber selection Vortex flowmeter on the pipeline design have higher requirements (such as straight pipe requirements, with the same diameter requirements, etc.), if the pipe design can not meet the requirements of the installation of the vortex flowmeter, the measurement characteristics will be generated Big deviation. Users need to choose according to their gas consumption vortex flowmeter caliber.
