style="text-indent:25px">差壓式流量計(jì)的檢測(cè)件按其作用原理可分為：節(jié)流裝置、水力阻力式、離心式、動(dòng)壓頭式、動(dòng)壓頭增益式及射流式幾大類。檢測(cè)件又可按其標(biāo)準(zhǔn)化程度分為二大類：標(biāo)準(zhǔn)的和非標(biāo)準(zhǔn)的。所謂標(biāo)準(zhǔn)檢測(cè)件是只要按照標(biāo)準(zhǔn)文件設(shè)計(jì)、制造、安裝和使用，無(wú)須經(jīng)實(shí)流標(biāo)定即可確定其流量值和估算測(cè)量誤差。非標(biāo)準(zhǔn)檢測(cè)件是成熟程度較差的，尚未列入國(guó)際標(biāo)準(zhǔn)中的檢測(cè)件。差壓式流量計(jì)是一類應(yīng)用較普遍的流量計(jì)，在各類流量?jī)x表中其使用量占居**。由于各種新型流量計(jì)的問(wèn)世，它的使用量百分?jǐn)?shù)逐漸下降，但目前仍是重要的一類流量計(jì)。</p><p style="text-indent:25px">孔板流量計(jì)工作原理：流體充滿管道，流經(jīng)管道內(nèi)的節(jié)流裝置時(shí)，流束會(huì)出現(xiàn)局部收縮，從而使流速增加，靜壓力低，于是在節(jié)流件前后便產(chǎn)生了壓力降，即壓差，介質(zhì)流動(dòng)的流量越大，在節(jié)流件前后產(chǎn)生的壓差就越大，所以孔板流量計(jì)可以通過(guò)測(cè)量壓差來(lái)衡量流體流量的大小。這種測(cè)量方法是以能量守衡定律和流動(dòng)連續(xù)性定律為基準(zhǔn)的。工作特點(diǎn)：①節(jié)流裝置結(jié)構(gòu)簡(jiǎn)單、牢固，性能穩(wěn)定可靠，使用期限長(zhǎng)，價(jià)格低廉;②應(yīng)用范圍廣，全部單相流皆可測(cè)量，部分混相流亦可應(yīng)用;③標(biāo)準(zhǔn)型節(jié)流裝置無(wú)須實(shí)流校準(zhǔn)，即可投用;④ 一體型孔板安裝更簡(jiǎn)單，無(wú)須引壓管，可直接接差壓變送器和壓力變送器。浮子流量計(jì)適用于小管徑和低流速。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="金屬浮子流量計(jì)市面價(jià),流量計(jì)"

style="text-indent:25px">電磁流量計(jì)安裝注意點(diǎn)：電磁流量計(jì)的傳感器應(yīng)垂直安裝，并且流體自下而上流動(dòng)，以滿足固、液兩項(xiàng)處于混合的狀態(tài)。原因是如介質(zhì)中有固體物(泥沙、小石子顆粒等)容易發(fā)生沉淀的情況。另外管路中有魚和雜草的情況魚在管路中的游動(dòng)，會(huì)造成流量計(jì)輸出的來(lái)回?cái)[動(dòng);掛在電極附近的雜草的來(lái)回?cái)[動(dòng)也會(huì)引起流量計(jì)的輸出不穩(wěn)定。在流量計(jì)上游入口處設(shè)置金屬濾網(wǎng)擋住魚和雜草進(jìn)入測(cè)量管內(nèi)。電磁流量計(jì)防止負(fù)壓的管路設(shè)置操作不當(dāng)將引起傳感器內(nèi)產(chǎn)生負(fù)壓。當(dāng)同時(shí)關(guān)閉流量計(jì)上、下游的閥門，若流體的溫度高于氣溫.冷卻后收縮，使管內(nèi)壓力有形成負(fù)壓的危險(xiǎn)。負(fù)壓造成襯里與金屬導(dǎo)管剝離，引起電極泄漏。氣體存在于流量計(jì)計(jì)量腔內(nèi)會(huì)造成流量計(jì)讀數(shù)不準(zhǔn)確。新型流量計(jì)銷售</p><p
