兩個(gè)傳感器之間的距離有嚴(yán)格的要求，一定要按規(guī)定的尺寸安裝，不同的安裝間距對(duì)測(cè)量準(zhǔn)確度產(chǎn)生不同的影響，有的甚至誤差很大。其它外界因素、耦合劑、信號(hào)電纜超聲波流量計(jì)的運(yùn)行特點(diǎn)及對(duì)便攜式超聲波流量計(jì)測(cè)量影響的誤差分析中，可以看出，要大限度地保證流量計(jì)測(cè)量的準(zhǔn)確性，還必須注意以下幾點(diǎn)：傳感器安裝處的壁面打磨干凈；傳感器的安裝位置應(yīng)盡可能在上游彎管的彎軸平面內(nèi)，以獲得彎管流暢畸變后較接近的平均值；傳感器安裝處和管壁反射處必須避開接口和焊縫；傳感器安裝處的管道襯里和垢層不能太厚；耦合劑一定要使用。

為焊接方便，常取上封頭與筒體等壁厚。反應(yīng)釜的夾套傳熱及其結(jié)構(gòu)整體夾套的結(jié)構(gòu)類型常用的夾套形式為整體夾套，結(jié)構(gòu)類型有四種其中a型僅圓筒的一部分有夾套，用在需加熱面積不大的場(chǎng)合。b型為圓筒的一部分和下封頭包有夾套，是常用的典型結(jié)構(gòu)。c型是考慮到筒體受外壓時(shí)為了減小筒體的計(jì)算長(zhǎng)度L，或者為了實(shí)現(xiàn)分段控制而采用分段夾套。d型為全包式夾套，與前三種比較，有大傳熱面積。當(dāng)夾套封閉件不是由夾套筒體直接彎制成形，封閉件與夾套筒體之間應(yīng)采用全焊透的對(duì)接焊，為保證焊透宜加墊板。
