水流指示器屬視鏡類儀表閥門，通過視窗能隨時觀察液體、氣體、蒸汽等介質的渾濁度且計量介質流動速度反應情況，是保障正常生產保證產品質量不可缺少的管道附件之一。

The water flow indicator belongs to the mirror type instrument valve, which can observe the turbidity of liquid, gas, steam and other media at any time through the window, and measure the flow rate reaction of the media. It is one of the indispensable pipeline accessories to ensure normal production and product quality.

水流指示器也可用于自動噴水滅火系統，它可以安裝在主供水管或橫桿水管上，給出某一分區域小區域水流動的電信號，此電信號可送到電控箱，但通常不用作啟動消防水泵的控制開關。

The water flow indicator can also be used in automatic sprinkler fire extinguishing systems. It can be installed on the main water supply pipe or crossbar water pipe, providing an electrical signal for the flow of water in a certain sub area or small area. This electrical signal can be sent to the electrical control box, but it is usually not used as a control switch to start the fire water pump.

水流指示器必須安裝在前后直管段長度不小于5倍的管道直徑，葉片安裝方向應注意箭頭方向與水流方向一致；水流指示器應和管道水平垂直安裝，若不能垂直安裝時，安裝后應檢查水流指示器的靈敏度，保證符合規定的要求。在管道水流≤15L/min不報警；≤37.5L/min時報警；

The water flow indicator must be installed on the front and rear straight pipe sections with a length of no less than 5 times the pipe diameter, and the installation direction of the blades should be consistent with the direction of the arrow and the water flow; The water flow indicator should be installed horizontally and vertically with the pipeline. If it cannot be installed vertically, the sensitivity of the water flow indicator should be checked after installation to ensure compliance with the specified requirements. No alarm when the water flow in the pipeline is ≤ 15L/min; ≤ Alarm at 37.5L/min;

流指示器安裝插入管道時，應將傳感葉片卷成圓筒狀。水流指示器請按接線圖接線；馬鞍式和卡箍式按說明書在管道上開口后即可安裝，但必須注意水流方向與箭頭一致；

When installing the flow indicator into the pipeline, the sensing blade should be rolled into a cylindrical shape. Please wire the water flow indicator according to the wiring diagram; The saddle type and clamp type can be installed after opening on the pipeline according to the instructions, but it must be noted that the direction of water flow is consistent with the arrow;

對夾式水流指示器在管道上應有法蘭，法蘭尺寸按說明書，DN80法蘭尺寸為1.0MPa級，注意水流方向與箭頭一致；水流指示器的靈敏度，出廠時已調整好，用戶一般可不必重新調試，若必須調試時，按調節靈敏度示意圖進行調節。

The clamp type water flow indicator should have a flange on the pipeline, and the flange size should follow the instructions. The DN80 flange size is 1.0MPa level, and attention should be paid to the direction of water flow consistent with the arrow; The sensitivity of the water flow indicator has been adjusted at the factory, and users generally do not need to readjust it. If it is necessary to adjust it, follow the sensitivity adjustment diagram for adjustment.
