流量儀表的選型對儀表能否成功使用往往起著很重要的作用，由于被測對象的復(fù)雜狀況以及儀表品種繁多、性能指標(biāo)各異，使得技術(shù)人員對儀表的選型感到困難。沒有一種十全十美的流量計，各類儀表都有各自的特點，選型的目的就是在眾多的品種中揚長避短，選擇自己zui合適的儀表。
一般選型可以從五個方面進行考慮，這五個方面為儀表性能方面、流體特性方面、安裝條件方面、環(huán)境條件方面和經(jīng)濟因素方面。五個方面的詳細(xì)分析如下：
1、儀表性能方面：準(zhǔn)確度、重復(fù)性、線性度、范圍度、流量范圍、信號輸出特性、響應(yīng)時間、壓力損失等；
2、流體特性方面：溫度、壓力、密度、粘度、化學(xué)腐蝕、磨蝕性、結(jié)垢、混相、相變、電導(dǎo)率、聲速、導(dǎo)熱系數(shù)、比熱容，等指數(shù)；
3、安裝條件方面：管道布置方向，流動方向，檢測件上下游側(cè)直管段長度、管道口徑、維修空間、電源、接地、輔助設(shè)備（過濾器、消氣器）、安裝、等；
4、環(huán)境條件方面：環(huán)境溫度、濕度、電磁干擾、安全性、防爆、管道振動等；
5、經(jīng)濟因素方面：儀表購置費、安裝費、運行費、校驗費、維修費、儀表使用壽命、備品備件等。
