電磁流量計(jì)有一系列優(yōu)良特性,可以解決其它流量計(jì)不易應(yīng)用的問(wèn)題,如臟污流、腐蝕流的測(cè)量。變送器的測(cè)量信號(hào)為很小的毫伏級(jí)電勢(shì)信號(hào)，除流量信號(hào)外，還夾雜一些與流量無(wú)關(guān)的信號(hào)，如同相電壓、正交電壓及共模電壓等。為了準(zhǔn)確測(cè)量流量，必須消除各種干擾信號(hào)，有效放大流量信號(hào)。應(yīng)該提高流量轉(zhuǎn)換器的性能，比較好采用微處理機(jī)型的轉(zhuǎn)換器，用它來(lái)控制勵(lì)磁電壓，按被測(cè)流體性質(zhì)選擇勵(lì)磁方式和頻率，可以排除同相干擾和正交干擾。但改進(jìn)的儀表結(jié)構(gòu)復(fù)雜，成本較高。流量計(jì)有渦輪流量計(jì)、渦街流量計(jì)、電磁流量計(jì)、多普勒超聲波流量計(jì)、熱線測(cè)速流量計(jì)；浙江金屬轉(zhuǎn)子流量計(jì)找哪家</p><p

1．孔板流量計(jì)安裝時(shí)應(yīng)配有一段測(cè)量管,至少保持**DN、后5DN的等徑直管段，以提高測(cè)量精度。 </p> <p> 2．在孔板流量計(jì)前后若需安裝閥門，比較好選閘閥且在運(yùn)行中全開(kāi)；調(diào)節(jié)閥則應(yīng)在下游5DN之后的管路中。 </p> <p> 3．引壓管路的內(nèi)徑與管路長(zhǎng)度和介質(zhì)臟污程度有關(guān)，通常在45米以內(nèi)用內(nèi)徑為8-12mm的管子。 </p> <p> 4．測(cè)量液體流量時(shí)引壓管水平段應(yīng)在同一水平面內(nèi)。若是在垂直管道上安裝節(jié)流件，引壓短管之間相距一定的距離（垂線方向），這對(duì)差壓變送器的零點(diǎn)有影響，應(yīng)通過(guò)“零點(diǎn)遷移”來(lái)校正。 </p> <p> 5．引壓管路應(yīng)有牢固的支架托承，兩根取壓管路應(yīng)盡可能互相靠近并遠(yuǎn)離熱源或震動(dòng)源，測(cè)量水蒸汽流量時(shí)，應(yīng)用保溫材料一同包扎，必須時(shí)（如氣溫0℃以下）加伴熱管防止結(jié)冰。在測(cè)量臟污流量時(shí)，應(yīng)附設(shè)隔離器或沉降器。 </p> <p> 6．引壓管路內(nèi)必須始終保持單相流體狀態(tài)。被測(cè)流體是氣體時(shí)，引壓管路（包括差壓計(jì)的壓力腔）內(nèi)全部是氣相；被測(cè)流體是液體時(shí)，引壓管路內(nèi)全部是液相，不能有氣泡。為此應(yīng)在引壓管路的比較低點(diǎn)裝排水閥或在比較高點(diǎn)裝排氣閥，在新裝或檢修差壓變送器時(shí)時(shí)應(yīng)特別注意。徐州液體渦輪流量計(jì)廠</p><p
