关键字:FMU30 http://www.dkmeh.com/ FMU30应用的现场的水池或者罐子内温度高,会影响超声波液位计一体式测量。 液体介质在30-40℃以下一般不会产生蒸汽和雾气,超过这个温度容易产生蒸汽或雾气,一体式FMU30发射的超声波在发射过程中穿过蒸汽会衰减一次,从液面反射回来的时候又要衰减一次,造成后回到探头的超声波信号很弱,所以测量不到。而且在这种环境下,超声波液位计探头容易结水珠,水珠会阻碍超声波的发射和接收。 面对FMU30这种情况的话,我们通常有以下这些解决方法: 1.要把量程加大,实际罐子高度是3米,要选择6米-9米的超声波液位计。可以减少或削弱蒸汽或者雾气对测量的影响。 2.探头上面涂抹硅脂,涂抹硅脂后的超声波探头明显结露减少。 3.发射强度增大,FMU30一体式可调发射强度,这样就可以穿透雾气。 4.滤波时间加大,加大滤波时间可减少二次波的接收,保数据的稳定。 5.传感器倾斜安装,露珠可顺着一侧流走,来缓解超声波液位计结露问题。 6.FMU30传感器探头装上恒温加热装置。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/568.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=1607415138703&bpp=14&bdt=334&idt=38&shv=r20201203&cbv=r20190131&ptt=9&saldr=aa&cookie=ID%3D5fb7eae809183df8-22fd78660ec40024%3AT%3D1602660717%3ART%3D1602660717%3AS%3DALNI_MYMQQp2TnvCbvJQtTRQsdNX_-71Bg&nras=1&correlator=8244060229663&frm=23&ife=1&pv=2&ga_vid=1151241174.1607415139&ga_sid=1607415139&ga_hid=825012765&ga_fc=0&nhd=1&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=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=21066699%2C21066792%2C42530672%2C21066922%2C21068084%2C21065725&oid=3&pvsid=800597877205110&pem=16&ref=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php%3Fadd_suc%3D1&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.j27y46jzc6fq&fsb=1&dtd=81" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransparency="true" scrolling="no" allowfullscreen="true" data-google-container-id="0.j27y46jzc6fq" data-load-complete="true"> |
