style="text-indent:25px">容積式流量計(jì)，又稱定排量流量計(jì)，簡(jiǎn)稱PD流量計(jì)，在流量?jī)x表中是精度較高的一類。它利用機(jī)械測(cè)量元件把流體連續(xù)不斷地分割成單個(gè)已知的體積部分，根據(jù)測(cè)量室逐次重復(fù)地充滿和排放該體積部分流體的次數(shù)來測(cè)量流體體積總量。容積式流量計(jì)按其測(cè)量元件分類，可分為橢圓齒輪流量計(jì)、刮板流量計(jì)、雙轉(zhuǎn)子流量計(jì)、旋轉(zhuǎn)活塞流量計(jì)、往復(fù)活塞流量計(jì)、圓盤流量計(jì)、液封轉(zhuǎn)筒式流量計(jì)、濕式氣量計(jì)及膜式氣量計(jì)等。優(yōu)點(diǎn)：（1）計(jì)量精度高；（2）安裝管道條件對(duì)計(jì)量精度沒有影響；（3）可用于高粘度液體的測(cè)量；（4）范圍度寬；（5）直讀式儀表無需外部能源可直接獲得累計(jì)總量，清晰明了，操作簡(jiǎn)便。</p><p

可以測(cè)量強(qiáng)腐蝕性介質(zhì)和非導(dǎo)電介質(zhì)的流量。(3) 超聲波流量計(jì)的測(cè)量范圍大，管徑范圍從20mm～5m。(4) 超聲波流量計(jì)可以測(cè)量各種液體和污水流量。(5) 超聲波流量計(jì)測(cè)量的體積流量不受被測(cè)流體的溫度、壓力、粘度及密度等熱物性參數(shù)的影響。可以做成固定式和便攜式兩種形式。浮子流量計(jì)的結(jié)構(gòu)簡(jiǎn)單，使用方便。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height:

將傳感器裝在遠(yuǎn)離振動(dòng)的地方或移至改變流態(tài)裝置的上游。2、讀數(shù)不正確。應(yīng)該是傳感器裝在水平管道的頂部或底部有沉淀物干擾超聲波信號(hào)。要么就是傳感器裝在水流向下的管道上管內(nèi)未充滿流體。處理方法：前者將傳感器裝在管道兩側(cè)、后者將傳感器裝在充滿流體的管段上。3、傳感器是好的,但流速低或沒有流速。可能是:A，由于管道內(nèi)的油漆、鐵銹未掃除干凈. 處理方法：重新掃除管道,安裝傳感器。B，管道面凹凸不平或安裝在焊接縫處。處理方法：將管道磨平或遠(yuǎn)離焊縫處安裝傳感器。C，管道圓度不好,內(nèi)表面不光滑,有管襯式結(jié)垢。處理方法：選擇鋼管等內(nèi)表面光滑管道材質(zhì)或襯的地方安裝傳感器。D，傳感器與管道耦合不好,耦合面有縫隙或氣泡。處理方法：重新安裝耦合劑。E，傳感器安裝在套管上,則會(huì)削弱超聲波信號(hào)。處理方法：將傳感器移到無套管的管段部位上。流量計(jì)在在實(shí)際使用過程中，檢查的周期是較長(zhǎng)的。管道流量計(jì)供應(yīng)商</p><p
