Product Description

Products:

ZSJZ series of water flow indicators are used in automatic sprinkler fire extinguishing system. They are installed on the main water supply pipe or horizontal trunk pipe of the system, or on the branch pipe of the system. When the system works, the pressure water flows in the pipe network. Driven by the water flow, the water flow indicator converts the water flow signal into electrical signal, and shows the fire occurs in a certain area of the system through the control box. It can also be used to start the control switch of fire pump.

The series of water flow indicators are divided into flange type, saddle type and groove type. Different types can be selected according to different places of use and engineering conditions. This series of water flow indicators can also be divided into two types: delay circuit and non-delay circuit. The circuit with delay has four stages, and the delay time can be selected between 2 and 90 seconds according to different conditions.
