E+H質(zhì)量流量計(jì)       E+H流量計(jì)             E+H原裝流量計(jì)上海報(bào)價(jià)

用以測(cè)量管路中流體流量（單位時(shí)間內(nèi)通過(guò)的流體體積）的儀表,。
　　流量測(cè)量方法和儀表的種類(lèi)繁多,，分類(lèi)方法也很多,。至今為止,，可供工業(yè)用的流量?jī)x表種類(lèi)達(dá)60種之多,。品種如此之多的原因就在于至今還沒(méi)找到一種對(duì)任何流體、任何量程,、任何流動(dòng)狀態(tài)以及任何使用條件都適用的流量?jī)x表,。
　　這60多種流量?jī)x表,每種產(chǎn)品都有它特定的適用性,也都有它的局限性。按測(cè)量對(duì)象劃分就有封閉管道和明渠兩大類(lèi);按測(cè)量目的又可分為總量測(cè)量和流量測(cè)量,其儀表分別稱(chēng)作總量表和流量計(jì),。
　　總量表測(cè)量一段時(shí)間內(nèi)流過(guò)管道的流量,，是以短暫時(shí)間內(nèi)流過(guò)的總量除以該時(shí)間的商來(lái)表示，實(shí)際上流量計(jì)通常亦備有累積流量裝置,，做總量表使用,，而總量表亦備有流量發(fā)訊裝置。因此,，以嚴(yán)格意義來(lái)分流量計(jì)和總量表已無(wú)實(shí)際意義,。
　　按測(cè)量原理分有力學(xué)原理、熱學(xué)原理,、聲學(xué)原理,、電學(xué)原理,、光學(xué)原理、原子物理學(xué)原理等,。
　　按照目前zui流行,、zui廣泛的分類(lèi)法,即分為:容積式流量計(jì)、差壓式流量計(jì),、浮子流量計(jì),、渦輪流量計(jì)、電磁流量計(jì),、流體振蕩流量計(jì)中的渦街流量計(jì),、質(zhì)量流量計(jì)和插入式流量計(jì)、探針式流量計(jì),，來(lái)分別闡述各種流量計(jì)的原理,、特點(diǎn)、應(yīng)用概況及國(guó)內(nèi)外的發(fā)展情況,。
　　按流量計(jì)機(jī)構(gòu)原理分有容積式流量計(jì)、葉輪式流量計(jì),、差壓式流量計(jì),、變面積式流量計(jì)、動(dòng)量式流量計(jì),、沖量式流量計(jì),、電磁流量計(jì)、超聲波流量計(jì),、質(zhì)量流量計(jì),、流體振蕩式流量計(jì)。
