1.Description

The water flow indicator is an integral part of the automatic sprinkler system. The flow of water in the spray pipe network is used to push the blade, and the micro switch is activated to convert the water flow signal into an electrical signal, and is connected with the controller to activate the automatic fire alarm system. It can be used to detect the operation of the automatic sprinkler system and to determine the area where the fire occurred. Suitable for wet, dry, recirculating and closed automatic water spray-foam systems.
