                超声波流量计安装7大要求

                超声波流量计安装7大要求
                超声波流量计的安装在所有的流量计安装中是方便简捷的,但为了保证测量精度,测量点应选择直管路部分,一般应遵循下列原则: 
                1.选择充满液体㊣ 的直管段,如管路的垂直段(流向由下向上为好)或充满液体的水平管道(整个管路中最低处为好),在安装与测量过程中,不得〗出现非满管情况; 
                2.测量位置应选◥在探头上游有大于10D和下游有5D直管段处; 
                3.测量↑点选择应尽可能远离泵,阀门等设备,避免其对测量ㄨ的干扰; 
                4.测量点选择应〇尽可能远离大功率电台,强磁场干扰源等; 
                5.充分考虑管内结垢状况,尽量选择无结垢的管段进行测量。结垢严『重时,应选择插入式探头。 
                6.选择管∮路管材应均匀密实,易于超声波传播ㄨ处; 
                7.管段初步安装位置选择好后,用于砂轮或钢锉将金属管表面◥打磨3倍的▓探头面积(约100mm范围),去掉锈迹油漆,使管@ 壁表面光滑平整,注意,表面应光泽均匀,无起伏ζ不平,与原ζ 管道有同样的弧度,切忌将安装点打磨△成平面,最后用酒精或汽油〓清洗干净。
