关键字:FMU30 http://www.dkmeh.com/ FMU30超声波液位计是根据时间行程原理来工作的,探头向物料表面方向发射超声波脉冲信号,在物料表面产生反射,反射回波信号被传感器接收。 FMU30计算探头发射和接收脉冲信号的运行时间差t,通过时间差t和声速C,计算探头至 物料表面间的距离D: D=C*U2 输入空罐高度E,可以按以下公式计算出物位: L=E-D FMU30具有干扰回波抑制功能,以确保干扰信号,比如来自边角、焊接点和安装过程中产生的干扰信号,不被误认为是物料表面的反射回波信号。除此之外,FMU30还有以下的特点: 1.使用G11/2或11/2 NPT螺纹接口进行安装; 2.四行纯文本显示的菜单式现场操作,快速、简单地进行仪表调试; 3.FMU30集成温度传感器,自动对受温度影响的声速进行校正; 4.非接触式测量方法最大限度地降低维护成本; 5.FMU30现场包络线显示,简单进行仪表故障诊断多达32点的线性化功能可将长度、体积或流量测量值转换成任意单位。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/564.htmlABSolute;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?guci=2.2.0.0.2.2.0.0&client=ca-pub-6745515041074118&ouTPUt=html&adk=1812271804&adf=3279755396&plat=1%3A32776%2C2%3A32776%2C8%3A134217728%2C9%3A134250504%2C10%3A32%2C11%3A32%2C16%3A8388608%2C17%3A32%2C24%3A32%2C25%3A32%2C30%3A1081344%2C32%3A32%2C40%3A32&format=0x0&url=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php%3Fact%3D1&ea=0&flash=32.0.0&pra=5&wgl=1&tt_state=W3siaXNzdWVyT3JpZ2luIjoiaHR0cHM6Ly9hZHNlcnZpY2UuZ29vZ2xlLmNvbSISInN0YXRlIjowfSx7Imlzc3Vlck9yaWdpbiI6Imh0dHBzOi8vYXR0ZXN0YXRpb24uYW5kcm9pZC5jb20iLCJzdGF0ZSI6MH1d&dt=1606896547402&bpp=3&bdt=1022&idt=32&shv=r20201112&cbv=r20190131&ptt=9&saldr=aa&cookie=ID%3D5fb7eae809183df8-22fd78660ec40024%3AT%3D1602660717%3ART%3D1602660717%3AS%3DALNI_MYMQQp2TnvCbvJQtTRQsdNX_-71Bg&nras=1&correlator=7345319888057&frm=23&ife=1&pv=2&ga_vid=1208279394.1606896547&ga_sid=1606896547&ga_hid=1419591300&ga_fc=0&iag=3&icsg=138&nhd=1&dssz=5&mdo=0&mso=0&u_tz=480&u_his=4&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=1243&bih=605&isw=730&ish=360&ifk=2699508910&scr_x=0&scr_y=0&eid=21066923&oid=3&pvsid=2466466950797711&pem=16&ref=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php&rx=0&eae=2&fc=1664&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=0.6gstqiv2yvqv&fsb=1&dtd=75" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransparency="true" scrolling="no" allowfullscreen="true" data-google-container-id="0.6gstqiv2yvqv" data-load-complete="true"> |
