水流指示器用于手動消防滅火系統中，可安裝在主給水管或橫桿給水管上，在一定分區的小范圍內給出水流的電信號。該電信號可發送電控箱或用于啟動消防泵的控制開關。那么它的安裝有哪些注意事項呢？

　　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?

　　水流指示器的安裝要注意水流的方向。并應水平安裝在系統管道上，切勿側向或倒置安裝，以免影響水流指示器的靈敏度。連接水流指示器的管道必須保證前后直管長度不小于管道直徑的5倍。在選擇水流量指示器時，應根據管道的公稱直徑，并根據技術參數表進行選擇。另外，延遲時間出廠時可以調整，調整范圍為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時報告火災的位置。信號閥用于顯示閥門的開啟狀態。如果沒有接線，消防員必須大聲說出來。沒有必要緊張。信號蝶閥只監測一個開閉信號，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.

　　一些工程設計并不能保證無差錯運行。噴水泵的啟動邏輯設置為報警閥和壓力開關。此外，操作是啟動泵。消防驗收時，更嚴格的檢查終端試水裝置開機后水流指示器是否動作。使用輸入模塊進行報告和監控。

　　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.

　　應將壓力開關信號閥和濕式報警閥上的水流指示器的信號發送給報警主機。報警主機接收水流指示器的動作信號和壓力開關信號。聯動泵信號閥的手動指令僅用于指示閥門開關狀態。是的，與泵無關。

　　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

　　壓力開關信號分為兩個控制輸出。泵房直接手動啟動水泵，并將其發送給消防控制中心的報警主機。如果遙控信號閥未接上，則不得指示閥門的啟閉狀態。報警主機上的顯示永遠不會出來。如果不接水流指示器，則永遠不會提示管道中有水流動，也永遠不會提示水泵聯動啟動。

　　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，川消人員認為規范要求兩者都應與主報警主機相連，接收水流指示器的動作信號和壓力開關的信號，手動命令水泵聯動。

　　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.
