数显型流量监控器
FS63系列
原理,结构                                                                             
    采用热传温差技术,在封闭的探头内放置发热模块及感染模块,探头的热量传导与被测量介质流速密切相关,当管道内介质以稳定的流速流动时,感应模块接收到发热模块感测的是一个固定值。当流过探头的流速发生变化时,感热模块会传出随之变化的温差信号,经过处理器将对应流速的结果输出。                                                                                   
                                                                                   
特点                                                                                   
    无活动部件,免维护,安装方便,一种型号适用多种管径要求.开关量连续可调,极低的压力损失,超清晰LED数码显示流量百分比,有多种输出功能可选择。满足不同用户对自动化控制的需求。                                                                                
                                                                                   
应用                                                                                   
    气液两用型,可用于气动和液压系统,可用于循环水、切削液及润滑油的断流监测,以及泵的空转保护。

安装                                                     
    基本安装方法是将其插入到管道上,并使探头充分与被测介质相接触。实际安装时应遵循以下几个原则:                                                                     
                                                                     
                                                                     
水平安装:                                                                   
           当安装在水平管道的上端时,应保证介质是满管,以防探头只接触到空气而未接触到介质。                                                              
                                                              
倒 装:                                                                
           当安装在水平管道的下端时,应保证管道底部没有沉淀物,以免探头被沉淀物覆盖而无法与探头充分接触。                                                           
                                                       
侧 装:                                                                
           当安装在管道侧面时,安装位置应避开沉淀物和空气。                                                                                          
垂直安装:                                                                   
           当垂直安装时,应装在由下至上流动的管段上。
