选用超声流量计要特别注意传感器的安装误差、管道内壁结垢、防腐层均匀与否，这些因素对测量结果影响很大。另据超声流量计的测量原理，只有流速分布均匀时才能保证测量的精确度，所以在流量计的上下游要有足够的直管段，参考各种资料及流量计的使用手册，要求上游最少不小于10D，下游大于5D。
由于自来水行业为连续生产，进行不间断计量是极为重要的，所以一般安装于管道上的流量计不能经常拆卸送检，一般做法是采用精确度较高的便携式超声流量计，按周期送国家认证单位进行校准，作为企业的标准器具，再用比对的方式定期检测在线流量计。这需要设计人员在设计时应根据使用单位要求，考虑将来生产管理的需要，预留出比对测量的空间，以方便用户，即将流量计井做得稍大一些，除安装固定式流量计外，还应如图1所示预留出便携式流量计测量的空间。
