電磁流量計應(yīng)用一直都非常，由于是為供水企業(yè)水計量商業(yè)專門設(shè)計的，具有防水、防腐、防干擾、防雷擊的能力。那么在電磁流量計使用中也肯定有一些題目，我們就收集來分析一下。一、傳感器接地的題目電磁流量計傳感器電極檢測的流量信號是毫伏級，且以傳感器內(nèi)流體的電位為基準(zhǔn)的，所以外來干擾對它的影響很大，因而，良好的接地很大程度上決定著流量計的丈量正確度。被測的流體本身作為電導(dǎo)體，必需排除其他不相關(guān)的電磁干擾。電極檢測出的電勢信號，不受外界寄生電勢的干擾。對傳感器應(yīng)有良好的單獨(dú)接地線，接地電阻小于10Ω。在連接傳感器的管道內(nèi)若涂有絕緣層或長短金屬管道時，傳感器兩側(cè)應(yīng)裝有接地環(huán)。

style="text-indent:25px">V錐流量計特點(diǎn)V錐流量計是從2000年左右才在中國國內(nèi)出現(xiàn)的流量計。其工作原理和孔板流量計相同。介質(zhì)通過V錐時,由于阻流件V錐的存在,使得流體的流過面積發(fā)生變化,流速發(fā)生變化,根據(jù)伯努利方程,流速變化引起了壓力的變化,該壓力的變化與流速之間有一定的關(guān)系。通過測量該壓力差達(dá)到測量流量的目的。雖然與孔板原理一樣,但是本質(zhì)的區(qū)別在于孔板為中心收縮型節(jié)流裝置,而V錐為邊壁收縮型節(jié)流裝置。眾所周知,測量范圍窄是制約孔板使用的主要原因。測量范圍窄的主要原因是:孔板的流量系數(shù)隨雷諾數(shù)的變化而變化較大,孔板的突然節(jié)流導(dǎo)致孔板后發(fā)生比較大的漩渦,該漩渦的存在直接導(dǎo)致信號噪聲比較大,從而限制了它的測量范圍。而V錐流量計克服了以上缺點(diǎn)。被測流體是液體時，引壓管路內(nèi)全部是液相，不能有氣泡。揚(yáng)州長頸噴嘴流量計源頭直供廠家</p><p
