关键字：流量变送器 http://www.whdkm.cn/ 孔板流量变送器是将标准孔板与多参数差压变送器配套组成的高量程比差压流量装置，可测量气体、蒸汽、液体及引的流量，要是想发挥它的作用，需要保证它的正常使用，需要满足以下条件：1. 工艺介质要持续的通过孔板流量变送器而且要充满导压管管，否则流量将无法测量。2. 孔板流量变送器的被测介质在物理上和热力学上须是均匀的单相流体，流经节流装置时不得发生相变，即使导压管内发生相变也不行；3. 流束应与管道平行，不得有旋转流；4. 流量变送器的节流装置所测得被测介质须是稳定流，或被测介质是稳定的缓慢变化的，不适用于脉动流和临界的流量测量。德科蒙过程控制（武汉）有限公司座机：027-88062221传真：027-88068180邮箱： sales@whdkm.com地址：武汉市武昌区中南国际城D座一单元901室原文出处：http://www.whdkm.cn/News_show.asp?id=878PARent;">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%3A32768%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=32.0.0&pra=5&wgl=1&adsid=NT&dt=1590393745879&bpp=15&bdt=69&idt=411&shv=r20200519&cbv=r20190131&ptt=9&saldr=aa&cookie=ID%3D5fb7eae809183df8%3AT%3D1588147156%3AS%3DALNI_MZhOWs11HQ-EEy1X6tCtUAbNrQ6cw&crv=1&nras=1&correlator=837544418851&frm=23&ife=1&pv=1&ga_vid=1433312263.1590393746&ga_sid=1590393746&ga_hid=1756311742&ga_fc=0&iag=3&icsg=42&nhd=1&dssz=4&mdo=0&mso=0&u_tz=480&u_his=6&u_java=0&u_h=1080&u_w=1920&u_ah=1030&u_aw=1920&u_cd=24&u_nplug=16&u_nmime=33&adx=-12245933&ady=-12245933&biw=1332&bih=649&isw=730&ish=360&ifk=2699508910&scr_x=0&scr_y=0&eid=21065532%2C21066085&oid=3&pvsid=4291150421730448&pem=16&ref=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php%3Fadd_suc%3D1&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.erop54xulsvt&fsb=1&dtd=431" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransparency="true" scrolling="no" allowfullscreen="true" data-google-container-id="0.erop54xulsvt" data-load-complete="true"> |
