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。

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。                                                              

                                                              

  :                                                                

           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。                                                           

                                                       

  :                                                                

           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。                 

                                         

双向挡片式流量开关

FB32

原理,结构                                                                              

插入式安装,机械式流量开关。内置微动触发开关。                                                    

特点                                                                                   

可双向感应流体有无流量状态。提供了两种长度的浆片。桨在安装过程中要加以修剪,以使开关在设定流量动作。当管道中流量增加,浆片开始绕开关的轴旋转,其产生的压降都小于3PSIG(0.21bar).                                                                                  

功能                                                                                   

通过检测管道中有无流量来断开或者闭合一个电路。●它通常运用于供暖、空调、制冷、水处理、增压供水、工业添加等系统。●通过其可以控制如下设备:水泵、燃烧器、压缩机、冷水机、电动阀、报警设备、工业添加设备等。●在供暖系统中,它的作用尤其重要,当锅炉系统回水流量过低或无流量时,它能迅速关闭燃烧器,防止锅炉系统干烧、超温,避免其他温度控制元件频繁介入
