在西门子质量流量计http://www.whamri.com/的选型一览表中可查得应用于含颗粒纤维浆液的可选的流量计有:差压式流量计中有弯管、楔型管、电磁流量计、多普勒法超声流量计、涡街流量计、靶式流量计、科里奥利质量流量计等。流量计测量和总量准确度和复性、线性度有较高要求。流量测量包括两种,即瞬时流量和累积流量,比如对分输站管道的原油属于贸易交接或石油化工管道进行连续配比生产或生产流程的过程控制等需要计量总量,间或辅以瞬时流量的观察。在有的工作场所对流量进行控制则需配备瞬时流量测量。据报道流量计测量煤粉含量高达65%水煤浆流量的多年应用经验,对测量浆液流量首选电磁流量计,除非所测量的浆液是非导电的或含有铁磁性颗粒,以及测量管道系统不允许截断以接入流量传感器,才选择其他流量计。 西门子质量流量计涡街流量计只能测量含有少量粉状固形物,固相含量较多或是纤维状会产生噪声而无法使用。因此,要根据现场计量的需要选择流量计。有些流量计如容积式流量计,涡轮流量计等,其测量原理是以机械计数或脉冲频率输出直接得到总量,其准确度较高,适用于计量总量,如配有相应的发讯装置也可输出流量。电话:027-87263542手机:18372021864PARent;">ABSolute;top:0;border:0;width:undefinedpx;height:undefinedpx;" SANdbox="allow-forms allow-pointer-lock allow-popUPS allow-popups-to-escape-sandbox allow-same-origin allow-scripts allow-top-navigation-by-user-activation" frameborder="0" src="https://googleads.g.doubleclick.net/pagead/ads?client=ca-pub-6745515041074118&ouTPUt=html&adk=1812271804&adf=3279755396&plat=1%3A32776%2C2%3A32776%2C8%3A32776%2C9%3A32776%2C16%3A8388608%2C17%3A32%2C24%3A32%2C25%3A32%2C30%3A1081344%2C32%3A32%2C40%3A32&guci=2.2.0.0.2.2.0.0&format=0x0&url=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php%3Fact%3D1&ea=0&flash=29.0.0&pra=5&wgl=1&dt=1588043008213&bpp=5&bdt=380&idt=83&shv=r20200423&cbv=r20190131&ptt=9&saldr=aa&cookie=ID%3Da07b3c4ba002eaff%3AT%3D1586760676%3AS%3DALNI_MZl9pNx2HQ9GFalqRptRGcqVZOiBA&crv=1&nras=1&correlator=905531286497&frm=23&ife=1&pv=2&ga_vid=401170480.1588043008&ga_sid=1588043008&ga_hid=1683549826&ga_fc=0&iag=3&icsg=42&nhd=1&dssz=4&mdo=0&mso=0&u_tz=480&u_his=5&u_java=0&u_h=1080&u_w=1920&u_ah=1030&u_aw=1920&u_cd=24&u_nplug=15&u_nmime=32&adx=-12245933&ady=-12245933&biw=1568&bih=760&isw=730&ish=360&ifk=2699508910&scr_x=0&scr_y=0&eid=21065472%2C21065474%2C21065532%2C182982100%2C182982300&oid=3&pvsid=841210033516890&pem=841&ref=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php&rx=0&eae=2&fc=1920&brdim=0%2C0%2C0%2C0%2C1920%2C0%2C1920%2C1030%2C730%2C360&vis=1&rsz=%7C%7Cs%7C&abl=NS&fu=8220&bc=31&ifi=0&uci=0.z4z862UPEpli&fsb=1&dtd=146" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransparency="true" scrolling="no" allowfullscreen="true" data-google-container-id="0.z4z862upepli" data-load-complete="true"> |
