德國(guó)E+H固定式超聲波流量計(jì)|E+H便攜式超聲波流量計(jì)
目前用的zui多的超聲波流量計(jì)主要有以下幾種：
E+H多譜勒式超聲波流量計(jì)
只能用于測(cè)量含有適量能反射超聲波信號(hào)的顆?；驓馀莸牧黧w，如工廠(chǎng)排放液、未處理的污水、雜質(zhì)含量穩(wěn)定的工廠(chǎng)過(guò)程液等。要注意它對(duì)被測(cè)介質(zhì)要求比較苛刻，不能是潔凈水，雜質(zhì)含量要相對(duì)穩(wěn)定，才可以正常測(cè)量。選擇此類(lèi)超聲波流量計(jì)即要對(duì)被測(cè)介質(zhì)心中有數(shù)，也要對(duì)所選用的超聲波流量計(jì)的性能、精度和對(duì)被測(cè)介質(zhì)的要求有深入的了解。
E+H便攜式超聲波流量計(jì)
用于臨時(shí)性測(cè)量，主要用于校對(duì)管道上已安裝的其它流量?jī)x表，進(jìn)行一個(gè)區(qū)域內(nèi)的流體平衡測(cè)試，檢查管道的當(dāng)時(shí)流量情況等。其優(yōu)點(diǎn)是方便、經(jīng)濟(jì)。
E+H時(shí)差式超聲波流量計(jì)
目前生產(chǎn)zui多、應(yīng)用范圍zui廣泛的超聲波流量計(jì)。它主要用來(lái)測(cè)量潔凈的流體流量，在自來(lái)水公司和工業(yè)用水領(lǐng)域，得到廣泛應(yīng)用。此外它也可以測(cè)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(cè)量，而且精度可達(dá)±1.5%。實(shí)際應(yīng)用表明，選用時(shí)差式超聲波流量計(jì)，對(duì)流體的測(cè)量都能達(dá)到滿(mǎn)意的效果。德國(guó)E+H固定式超聲波流量計(jì)|E+H便攜式超聲波流量計(jì)
E+H管段式超聲波流量計(jì)
精度zui高，可達(dá)到±0.5%，而且不受管道材質(zhì)、襯里的限制，適用于流量測(cè)量精度要求高的場(chǎng)合。但隨著管徑的增大，成本也會(huì)增加，通常情況下，選用中小口徑的管段式超聲波流量計(jì)較為經(jīng)濟(jì)。

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(jié)垢及管壁對(duì)超聲波信號(hào)衰減的影響，測(cè)量穩(wěn)定性更高，也大大減小了維護(hù)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(yīng)用正在不斷推廣。
