The welded water flow indicator is an auxiliary alarm device in the automatic sprinkler system. Generally installed on the water distribution main pipes or water distribution pipes in each zone of the system, it can convert water flow signals into electrical signals to monitor and alarm the system. The water flow indicator is composed of a body, a micro switch, a paddle, a flange (or thread) tee, etc. When a fire alarm occurs in a certain area of the system and the sprinkler nozzle sprays water, the signal of water flow in the pipe network is converted into an electrical signal output, which is transmitted to the module or control center to display the fire location and realize regional alarm. When the nozzle stops spraying water, the paddle automatically resets to the servo state and the alarm disappears.
