关键字：FMU30 http://www.dkmeh.com/ FMU30的工作原理是它向液面发出一个超声波脉冲，经过一段时间，FMU30的传感器接收到从液面反射回的信号，信号经过变送器电路的选择和处理，根据超声波物位计发出和接收超声波的时间差，计算出液面到传感器的距离。 FMU30要想在使用中发挥出其功效首先就要选择好它的安装位置，安装位置有着以下的安装需求。 1.FMU30传感器发射面最高液位的距离，应大于选购仪表的盲区，若是不得不选择小于选购仪表的盲区，那么需加装延伸管，延伸管管径大于120mm，长度0.35m～0.50m，垂直安装，内壁光滑，罐上开孔应大于延伸管内径。或者可以将管子直接到罐底，管径大于80mm，管底留孔便于液体流入； 2.传感器发射面到最低液位的距离，应小于选购仪表的量程； 3.传感器的安装位置应尽量避开正下方进、出料口等液面剧烈波动的位置； 4.FMU30若池壁或罐壁不光滑，仪表需离开池壁或罐壁0.3m以上。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原文出处：http://www.dkmeh.com/a/news/522.htmlPARent;">ABSolute;top:0;border:0;width:undefinedpx;height:undefinedpx;" SANdbox="allow-forms 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%2C9%3A32776%2C10%3A32%2C11%3A32%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&dt=1601280673405&bpp=15&bdt=84&idt=265&shv=r20200923&cbv=r20190131&ptt=9&saldr=aa&cookie=ID%3D5fb7eae809183df8%3AT%3D1588147156%3AS%3DALNI_MZhOWs11HQ-EEy1X6tCtUAbNrQ6cw&nras=1&correlator=7274520250596&frm=23&ife=1&pv=2&ga_vid=2055185846.1601280674&ga_sid=1601280674&ga_hid=583451834&ga_fc=0&iag=3&icsg=42&nhd=1&dssz=4&mdo=0&mso=0&u_tz=480&u_his=8&u_java=0&u_h=1080&u_w=1920&u_ah=1030&u_aw=1920&u_cd=24&u_nplug=17&u_nmime=34&adx=-12245933&ady=-12245933&biw=1332&bih=649&isw=730&ish=360&ifk=2699508910&scr_x=0&scr_y=0&eid=21067492&oid=3&pvsid=1497684075039043&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=8204&bc=31&ifi=0&uci=0.9obv19pyng3g&fsb=1&dtd=307" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransparency="true" scrolling="no" allowfullscreen="true" data-google-container-id="0.9obv19pyng3g" data-load-complete="true"> |
