只有當(dāng)流量計(jì)正確使用并及時(shí)的維護(hù)時(shí)，流量計(jì)才能以規(guī)定的精度運(yùn)行。 </p> <p> （1）使用流量計(jì)時(shí)應(yīng)按照規(guī)定的流量范圍、工作壓力和工作溫度，不得隨意超出范圍以確保測量精度及使用壽命。 </p> <p> （2）對(duì)于運(yùn)行中的流量計(jì)，應(yīng)按時(shí)巡檢，并記錄有關(guān)運(yùn)行參數(shù)，如溫度、濕度、壓力、噪聲及有無滲漏等。 </p> <p> （3）長時(shí)間不用的流量計(jì)應(yīng)將殼內(nèi)殘留的流體泄放掉，根據(jù)需要涂防腐劑。 </p> <p> （4）對(duì)于一些國家特定的流量計(jì)量儀表，按規(guī)定按期強(qiáng)制標(biāo)定。流量計(jì)又分為有差壓式流量計(jì)、容積流量計(jì)、電磁流量計(jì)、超聲波流量計(jì)、渦輪流量計(jì)和渦街流量計(jì)等等。</p><div style="width:100%;text-align: center;"><img

渦街流量計(jì)安裝對(duì)直管段的要求：正確地選擇安裝點(diǎn)和正確安裝流量計(jì)都是非常重要的環(huán)節(jié)，若安裝環(huán)節(jié)失誤輕者影響測量精度，重者會(huì)影響流量計(jì)的使用壽命，甚至?xí)p壞流量計(jì)。渦街流量計(jì)安裝對(duì)直管段的要求是非常重要的。它的詳細(xì)要求如***量計(jì)對(duì)安裝點(diǎn)上的上下游直管段一定的要求，否則會(huì)影響測量精度。若流量計(jì)安裝點(diǎn)上的上游有漸縮管，流量計(jì)上游應(yīng)有不小于15D(D為管道直徑)的等徑直管段，下游應(yīng)有不小于5D的等徑直管段。若流量計(jì)安裝點(diǎn)上的上游有漸擴(kuò)管，流量計(jì)上游應(yīng)有不小于18D(D為管道直徑)的等徑直管段，下游應(yīng)有不小于5D的等徑直管段若流量計(jì)安裝點(diǎn)上游有90°彎頭或下行接頭，流量計(jì)上游應(yīng)有不小于**的等徑直管段，下游應(yīng)有不小于5D的等徑直管段。若流量計(jì)安裝點(diǎn)上游在同一平面上有90°彎頭，流量計(jì)上游應(yīng)有不小于25D的等徑直管段，下游應(yīng)有不小于5D的等徑直管段。流量調(diào)節(jié)閥或壓力調(diào)節(jié)閥盡量安裝在流量計(jì)下游5D以遠(yuǎn)處，若必須安裝在流量計(jì)的上游，流量計(jì)上游應(yīng)有不小于25D的等徑直管段，下游應(yīng)有不小于5D的等徑直管段。流量計(jì)上游若有活塞式或柱塞式泵，活塞式或羅茨式風(fēng)機(jī)、壓縮機(jī)，流量計(jì)上游應(yīng)有不小于25D的等徑直管段，下游應(yīng)有不小于5D的等徑直管段。玻璃管浮子流量計(jì)結(jié)構(gòu)簡單，價(jià)格低廉。只要在現(xiàn)場指示流量者使用方便。橢圓齒輪流量計(jì)分類</p><p

電磁流量計(jì)廣應(yīng)用于污水，氟化工，生產(chǎn)用水，自來水行業(yè)以及醫(yī)藥，鋼鐵等等諸多方面。由于原理決定了它只能測導(dǎo)電液體。雖說它在可靠性和穩(wěn)定性方面都比其它種類的流量計(jì)要好許多，但客戶在實(shí)際使用過程中，還是會(huì)發(fā)生一些問題，下面我就電磁流量計(jì)在選型和安裝上詳細(xì)說一下：一，和其它流量計(jì)一樣，雖然電磁流量計(jì)它的測量范圍比是30：1，比渦街流量計(jì)和差壓式流量計(jì)都要高，但也是有限制的，許多客戶定表時(shí)，常常把它和水表相比較，以為可以測量很低的流速，一般情況下，它只能測。所以定貨初期對(duì)流量范圍比要搞清楚。定貨時(shí)不能按原先管道口徑來定貨，比較好按你實(shí)際流量來定儀表口徑。二，和其它流量計(jì)一樣，電磁流量計(jì)對(duì)安裝前后直管道也有要求，只不過比其它類流量計(jì)要求更低，但關(guān)健一點(diǎn)要滿足：就是滿管，再滿管。不滿管的情況下容易引起流量計(jì)亂跳：三，和其它流量計(jì)一樣，電磁流量計(jì)也有防護(hù)等級(jí)，一般一體式的防護(hù)等級(jí)為IP65，分體式的為IP68(針對(duì)傳感器而言)，如果客戶對(duì)儀表安裝環(huán)境有要求，安裝地點(diǎn)在地下陰井或其它一些潮濕的地方，建議客戶選用分體式的。以免選錯(cuò)對(duì)儀表造成損害。渦輪流量計(jì)推薦廠家</p><p
