Introduction to ZSJZ Trench Water Flow Indicator

ZSJZ groove water flow indicator is an alarm device used in automatic sprinkler fire extinguishing systems to convert water flow signals into electrical signals. It is an auxiliary alarm device in the automatic sprinkler fire extinguishing system.

Application of ZSJZ groove water flow indicator

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