水流指示器用于手动消防灭火系统中，可安装在主给水管或横杆给水管上，在一定分区的小范围内给出水流的电信号。该电信号可发送电控箱或用于启动消防泵的控制开关。那么它的安装有哪些注意事项呢？

　　The water flow indicator is used in manual fire extinguishing system. It can be installed on the main water supply pipe or cross rod water supply pipe to give electrical signals of water flow in a small area of a certain partition. The electrical signal can be sent to the electrical control box or the control switch used to start the fire pump. So what are the precautions for its installation?

　　水流指示器的安装要注意水流的方向。并应水平安装在系统管道上，切勿侧向或倒置安装，以免影响水流指示器的灵敏度。连接水流指示器的管道必须保证前后直管长度不小于管道直径的5倍。在选择水流量指示器时，应根据管道的公称直径，并根据技术参数表进行选择。另外，延迟时间出厂时可以调整，调整范围为2-90S。

　　The installation of the flow indicator should pay attention to the direction of the flow. And should be installed horizontally on the system pipeline, do not side or upside down installation, so as not to affect the sensitivity of the water flow indicator. The pipe connecting the flow indicator must be at least 5 times the pipe diameter. The water flow indicator shall be selected according to the nominal diameter of the pipe and the technical parameter table. In addition, the delay time can be adjusted before delivery, ranging from 2-90s.

　　水流指示器的作用是及时报告火灾的位置。信号阀用于显示阀门的开启状态。如果没有接线，消防员必须大声说出来。没有必要紧张。信号蝶阀只监测一个开闭信号，水流指示器稍微重要一些。

　　The function of the water flow indicator is to report the location of the fire in time. Signal valve is used to show the valve opening state. If there's no wiring, firefighters have to speak up. There's no need to be nervous. Signal butterfly valves monitor only one on/off signal; flow indicator is slightly more important.

　　一些工程设计并不能保证无差错运行。喷水泵的启动逻辑设置为报警阀和压力开关。此外，操作是启动泵。消防验收时，更严格的检查终端试水装置开机后水流指示器是否动作。使用输入模块进行报告和监控。

　　Some engineering designs do not guarantee error-free operation. The starting logic of the spray pump is set as alarm valve and pressure switch. In addition, the operation is to start the pump. During fire acceptance, check whether the water flow indicator works after the terminal water test device is started strictly. It is best to use input modules for reporting and monitoring.

　　应将压力开关信号阀和湿式报警阀上的水流指示器的信号发送给报警主机。报警主机接收水流指示器的动作信号和压力开关信号。联动泵信号阀的手动指令仅用于指示阀门开关状态。是的，与泵无关。

　　Signals from the pressure switch signal valve and the water flow indicator on the wet alarm valve shall be sent to the alarm host. The alarm host receives the action signal and pressure switch signal of the water flow indicator. The manual instruction of the linkage pump signal valve is only used to indicate the valve switching state. Yeah, it's not about pumps

　　压力开关信号分为两个控制输出。泵房直接手动启动水泵，并将其发送给消防控制中心的报警主机。如果遥控信号阀未接上，则不得指示阀门的启闭状态。报警主机上的显示永远不会出来。如果不接水流指示器，则永远不会提示管道中有水流动，也永远不会提示水泵联动启动。

　　The pressure switch signal is divided into two control outputs. The pump room manually starts the water pump and sends it to the alarm host in the fire control center. If the remote signal valve is not connected, it shall not indicate the valve opening and closing state. The display on the alarm host will never come out. If the water flow indicator is not connected, it will never indicate that there is water flowing in the pipe, nor will it indicate that the pump linkage starts.

　　因此，川消人员认为规范要求两者都应与主报警主机相连，接收水流指示器的动作信号和压力开关的信号，手动命令水泵联动。

　　Therefore, sichuan consumption personnel think that the specification requires that both should be connected with the main alarm host, receive the flow indicator signal and pressure switch signal, manual command pump linkage.
