水流指示器是自动喷水灭火系统中的重要组成部件．是将水流信号转换成电信号的一种报警装置，安装在自动喷水灭火系所保护的每个防火分区和每个楼层的配水管道中。当管网中水流量大于 15L ／ min 时，水流指示器的叶片受水流冲击移动，改变微动开关的开关状态，发出报警信号．起到监测和指示报警区域的作用。水流指示器应竖直安装在管网水平管道上，其动作方向应和水流一致，水流指示器的周围必须留有一定的空间，便于安装维修操作。
水流指示器安装位置前后连接有长度 1 m 以上的直管段，以避免水流干扰，水流指示器在运输和安装过程中，应尽量避免剧烈碰撞，防止损坏工作部件或使预先调定的工作参数漂移。
本公司生产的水流指示器灵敏度已经调试合格，安装前后不允许自行拆卸调整。如确有问题，经我公司确认后，予以重新调整或更换。
The water flow indicator, crucial part of the sprinkler system, is a warning device that turns water flow signal into one of electronic, and installed each fire zone protected by the sprinkler system and water distribution pipe of each floor.When the water flow in the pipe network is over15L/min, the vane of the water flow indicator will change micro switch to send alerting signal, which serves monitoring and indicating the alert zone. The water flow indicator should be vertically setup on the horizontal pipeline of the pipe network and its moving direction same as the water flow. And there must be room for operation of installment and maintenance.
1meter long or above straight pipe should better be linked on the front and back of the water flow indicator to avoid interference of water flow. During the process of transportation and installment, the water flow indicator shall to the greatest extent be averted from violent crash, in case of damage of working parts or change of pre-set working parameter.
The sensitivity of the water flow indicator produced by our company has been calibrated and self disassembly and adjustment are prohibited. In the event of problem, we will readjust or change the product after confirmation.
