1. Description of Flange-Type Water Flow Indicator ZSJZ

The water flow indicator is a component of the automatic sprinkler system. It utilizes the flow of water in the sprinkler pipeline to drive a vane, which activates a microswitch, thereby converting the water flow signal into an electrical signal. Connected to a controller, it initiates the automatic fire alarm system. It can be used to detect the operation of the automatic sprinkler system and identify the area where a fire has occurred. It is suitable for wet, dry, recycling, and closed automatic water-foam combined systems.
