水流指示器属视镜类仪表阀门，通过视窗能随时观察液体、气体、蒸汽等介质的浑浊度且计量介质流动速度反应情况，是保障正常生产保证产品质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动喷水灭火系统，它可以安装在主供水管或横杆水管上，给出某一分区域小区域水流动的电信号，此电信号可送到电控箱，但通常不用作启动消防水泵的控制开关。

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.

水流指示器必须安装在前后直管段长度不小于5倍的管道直径，叶片安装方向应注意箭头方向与水流方向一致；水流指示器应和管道水平垂直安装，若不能垂直安装时，安装后应检查水流指示器的灵敏度，保证符合规定的要求。在管道水流≤15L/min不报警；≤37.5L/min时报警；

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;

流指示器安装插入管道时，应将传感叶片卷成圆筒状。水流指示器请按接线图接线；马鞍式和卡箍式按说明书在管道上开口后即可安装，但必须注意水流方向与箭头一致；

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;

对夹式水流指示器在管道上应有法兰，法兰尺寸按说明书，DN80法兰尺寸为1.0MPa级，注意水流方向与箭头一致；水流指示器的灵敏度，出厂时已调整好，用户一般可不必重新调试，若必须调试时，按调节灵敏度示意图进行调节。

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.
