关键字:FMU30 http://www.dkmeh.com/ 一体式 FMU30在现场工作的时候可能会出现工作不正常的情况,今天我们主要给大家介绍的是现场容器里面有搅拌,液体波动比较大,影响超声波一体式FMU30的测量这种情况。 出现这种情况的话,FMU30出现的故障现象是无信号或者数据波动厉害。这是由于液位计说的测量几米距离,都是指平静的水面。比如5米量程的FMU30,一般是指测量平静的水面大距离是5米,实际出厂会做到6米。遇到容器里面有搅拌的情况下,水面不是平静的,反射信号会减弱到正常信号的一半以下。 针对以上的情况,可以用下面的做法: 1.建议把二线制FMU30改为四线制的; 2.选用更大量程的FMU30,如果实际量程是5米,那就要用10米或者15米的超声波液位计来测量; 3.如果不换一体式FMU30,而且罐子内液体无粘性,还可以安装导波管,把液位计探头放在导波管内测量液位计高度,因为导波管内的液面基本是平稳的。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/526.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?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&tt_state=W3siaXNzdWVyT3JpZ2luIjoiaHR0cHM6Ly9hZHNlcnZpY2UuZ29vZ2xlLmNvbSISInN0YXRlIjowfV0.&dt=1602316442203&bpp=20&bdt=312&idt=226&shv=r20201007&cbv=r20190131&ptt=9&saldr=aa&cookie=ID%3D5fb7eae809183df8%3AT%3D1588147156%3AS%3DALNI_MZhOWs11HQ-EEy1X6tCtUAbNrQ6cw&nras=1&correlator=7498014202424&frm=23&ife=1&pv=1&ga_vid=262462960.1602316442&ga_sid=1602316442&ga_hid=2028380652&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=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=21066468&oid=3&pvsid=3267268253851601&pem=16&ref=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php%3Fact%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.o30kbs8z46lq&fsb=1&dtd=257" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransparency="true" scrolling="no" allowfullscreen="true" data-google-container-id="0.o30kbs8z46lq" data-load-complete="true"> |
