德國E+H固定式超聲波流量計|E+H便攜式超聲波流量計
目前用的zui多的超聲波流量計主要有以下幾種：
E+H多譜勒式超聲波流量計
只能用于測量含有適量能反射超聲波信號的顆?；驓馀莸牧黧w，如工廠排放液、未處理的污水、雜質(zhì)含量穩(wěn)定的工廠過程液等。要注意它對被測介質(zhì)要求比較苛刻，不能是潔凈水，雜質(zhì)含量要相對穩(wěn)定，才可以正常測量。選擇此類超聲波流量計即要對被測介質(zhì)心中有數(shù)，也要對所選用的超聲波流量計的性能、精度和對被測介質(zhì)的要求有深入的了解。
E+H便攜式超聲波流量計
用于臨時性測量，主要用于校對管道上已安裝的其它流量儀表，進行一個區(qū)域內(nèi)的流體平衡測試，檢查管道的當時流量情況等。其優(yōu)點是方便、經(jīng)濟。
E+H時差式超聲波流量計
目前生產(chǎn)zui多、應用范圍zui廣泛的超聲波流量計。它主要用來測量潔凈的流體流量，在自來水公司和工業(yè)用水領域，得到廣泛應用。此外它也可以測量雜質(zhì)含量不高（含量小于10g/L，粒徑小于1mm）的均勻流體，如污水的測量，而且精度可達±1.5%。實際應用表明，選用時差式超聲波流量計，對流體的測量都能達到滿意的效果。德國E+H固定式超聲波流量計|E+H便攜式超聲波流量計
E+H管段式超聲波流量計
精度zui高，可達到±0.5%，而且不受管道材質(zhì)、襯里的限制，適用于流量測量精度要求高的場合。但隨著管徑的增大，成本也會增加，通常情況下，選用中小口徑的管段式超聲波流量計較為經(jīng)濟。
E+H固定式超聲波流量計
如果有足夠的安裝空間，使用插入式換能器代替外貼式換能器，*消除了管襯、結垢及管壁對超聲波信號衰減的影響，測量穩(wěn)定性更高，也大大減小了維護工作量。而且，由于插入式換能器也可以不斷流安裝，所以其應用正在不斷推廣。
