流量仪表的选型对仪表能否成功使用往往起着很重要的作用，由于被测对象的复杂状况以及仪表品种繁多、性能指标各异，使得技术人员对仪表的选型感到困难。没有一种十全十美的流量计，各类仪表都有各自的特点，选型的目的就是在众多的品种中扬长避短，选择自己zui合适的仪表。

　　一般选型可以从五个方面进行考虑，这五个方面为仪表性能方面、流体特性方面、安装条件方面、环境条件方面和经济因素方面。五个方面的详细分析如下：

　　1、仪表性能方面：准确度、重复性、线性度、范围度、流量范围、信号输出特性、响应时间、压力损失等；

　　2、流体特性方面：温度、压力、密度、粘度、化学腐蚀、磨蚀性、结垢、混相、相变、电导率、声速、导热系数、比热容，等指数；

　　3、安装条件方面：管道布置方向，流动方向，检测件上下游侧直管段长度、管道口径、维修空间、电源、接地、辅助设备（过滤器、消气器）、安装、等；

　　4、环境条件方面：环境温度、湿度、电磁干扰、安全性、防爆、管道振动等；

　　5、经济因素方面：仪表购置费、安装费、运行费、校验费、维修费、仪表使用寿命、备品备件等。
