关键字：雷达液位计 http://www.dkmcn.com/ 众所周知，雷达液位计在选型的时候要根据容器的体积和形状来判断，还要考虑腐蚀性、泡沫、蒸汽等因素来进行选择。雷达液位计由于非接触性质常常测量腐蚀性较强的介质，但是不同程度的腐蚀性选择的雷达液位计也会有所不同。高频喇叭口雷达的法兰和喇叭口默认是304材质,遇到一般腐蚀性液体可以选用316材质,遇到盐酸、硝酸等强腐蚀液体,就要用喷涂四氧的方式。导波雷达液位计的法兰和缆绳是304材质,遇到一般腐蚀性液体可以选用316材质,遇到盐酸、硝酸等强腐蚀性液体可以选用衬聚四氟乙烯的。低频喇叭口雷达的法兰和喇叭口默认是304材质,遇到一般腐蚀性液体可以选用316材质,遇到盐酸、硝酸等强腐蚀液体,就要用喷涂四氟的方式。在遇到盐酸、硝酸等强腐蚀液体,更适合的是低频棒式雷达和高频棒式雷达。这两种雷达液位计都是为了在强腐蚀性环境下而设计的。要注意的是低频棒式雷达的盲区比较大,有0.5-0.7米,在小罐子上就不适合了。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.dkmcn.com/News_show.asp?id=899ABSolute;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%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=1599724429138&bpp=5&bdt=512&idt=12&shv=r20200901&cbv=r20190131&ptt=9&saldr=aa&cookie=ID%3D5fb7eae809183df8%3AT%3D1588147156%3AS%3DALNI_MZhOWs11HQ-EEy1X6tCtUAbNrQ6cw&nras=1&correlator=8132486781419&frm=23&ife=1&pv=2&ga_vid=627743386.1599724429&ga_sid=1599724429&ga_hid=1159636576&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=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=42530621%2C21067034&oid=3&pvsid=617151859226992&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.h8l2r1aehpem&fsb=1&dtd=35" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransparency="true" scrolling="no" allowfullscreen="true" data-google-container-id="0.h8l2r1aehpem" data-load-complete="true"> |
