E+H超聲波流量計(jì)的主要特點(diǎn)是：流體中不插入任何元件，對(duì)流速無(wú)影響，也沒(méi)有壓力損失；能用于任何液體，特別是具有高黏度、強(qiáng)腐蝕，非導(dǎo)電性等性能的液體的流量測(cè)量，也能測(cè)量氣體的流量；對(duì)于大口徑管道的流量測(cè)量，不會(huì)因管徑大而增加投資；量程比較寬，可達(dá)5：1；輸出與流量之間呈線性等優(yōu)點(diǎn)。

超聲波流量計(jì)測(cè)量原理：當(dāng)超聲波束在液體中傳播時(shí)，液體的流動(dòng)將使傳播時(shí)間產(chǎn)生微小變化，并且其傳播時(shí)間的變化正比于液體的流速，其關(guān)系符合下列表達(dá)式 　　
其中 　　
θ為聲束與液體流動(dòng)方向的夾角 　　
M 為聲束在液體的直線傳播次數(shù) 　　
D 為管道內(nèi)徑 　　
Tup 為聲束在正方向上的傳播時(shí)間 　　
Tdown為聲束在逆方向上的傳播時(shí)間 　　
ΔT=Tup –Tdown 　　
設(shè)靜止流體中的聲速為c，流體流動(dòng)的速度為u，傳播距離為L(zhǎng)，當(dāng)聲波與流體流動(dòng)方向*時(shí)（即順流方向），其傳播速度為c+u；反之，傳播速度為c-u.在相距為L(zhǎng)的兩處分別放置兩組超聲波發(fā)生器和接收器（T1,R1）和（T2,R2）。當(dāng)T1順?lè)较?，T2逆方向發(fā)射超聲波時(shí)，超聲波分別到達(dá)接收器R1和R2所需要的時(shí)間為t1和t2,則 　　
t1=L/（c+u） t2=L/（c-u） 　　
由于在工業(yè)管道中，流體的流速比聲速小的多，即c>>u,因此兩者的時(shí)間差為 ▽t=t2-t1=2Lu/cc 由此可知，當(dāng)聲波在流體中的傳播速度c已知時(shí)，只要測(cè)出時(shí)間差▽t即可求出流速u，進(jìn)而可求出流量Q。利用這個(gè)原理進(jìn)行流量測(cè)量的方法稱為時(shí)差法。此外還可用相差法、頻差法等。

E+H超聲流量計(jì)的分類　　
插入式超聲流量計(jì)：可不停產(chǎn)安裝和維護(hù)。采用陶瓷傳感器，使用我公司鉆孔裝置進(jìn)行不停產(chǎn)安裝。一般為單聲道測(cè)量，為了提高測(cè)量準(zhǔn)確度，可選擇三聲道。
管段式超聲流量計(jì)：需切開管路安裝，但以后的維護(hù)可不停產(chǎn)?？蛇x擇單聲道或三聲道傳感器。
外夾式超聲流量計(jì)：能夠完成固定和移動(dòng)測(cè)量。采用耦合劑（室溫固化的硅橡膠或高溫長(zhǎng)鏈聚合油脂）安裝，安裝時(shí)不損壞管路。
便攜式超聲流量計(jì)：便攜使用，內(nèi)置可充電鋰電池，適合移動(dòng)測(cè)量，配接磁性傳感器。
1、非接觸式測(cè)量方式、體積小、攜帶方便
2、適用于現(xiàn)場(chǎng)測(cè)量各種尺寸管道導(dǎo)聲介質(zhì)
3、內(nèi)置鎳氫充電電池工作時(shí)間達(dá)20小時(shí)以上
4、用戶界面靈活，使用簡(jiǎn)單
5、智能型現(xiàn)場(chǎng)打印功能，保證流量數(shù)據(jù)的完整
6、配備一體式鋁合金防護(hù)箱，可在野外惡劣環(huán)境中使用
手持式超聲流量計(jì)：體積小，重量輕，內(nèi)置可充電鋰電池，手持使用，配接磁性傳感器。
防爆型超聲流量計(jì)：用于爆炸性環(huán)境液體流量測(cè)量，為防爆兼本安型。即轉(zhuǎn)換器為防爆型，傳感器為本質(zhì)安全型。
