WaterFlow Detector
Size (inch): 2-3-4-5-6-8
Maximum working pressure: 450 psi
The flow switch or fire extinguishing system detector is an important component in sprinkler lines. In its body, there is a paddle blade with a micro switch. When water flows in the fire sprinkler pipeline and its paddle blade is activated, an alarm signal is sent to the fire alarm system by the micro switch. The detector operates with the help of the force exerted by the fluid when moving.
A fire flow switch is a vital piece of equipment in fire extinguishing systems that, in the event of a fire, disconnects the power supply and allows the fire extinguishing system to be activated automatically. This equipment acts as a bridge between the fire department and the electrical equipment of the building and is of great importance in preventing the spread of fire and protecting people and property. The use of a fire flow switch as an essential safety device in any commercial or industrial building is recommended so that in the event of a fire, the fire extinguishing system is automatically activated and further damage is prevented. These devices are placed in the path of the fluid flow in the pipe and, using the pressure force generated by the flow with other parts of the system, give the necessary command to change the necessary system mechanism. Commands can include turning on or off a pump or ventilation fan or turning on an alarm, opening and closing a solenoid valve, etc. There are different types of flow switches, the paddle type of which is suitable for general use in controlling the flow of liquids, especially water.
The water flow indicator should be installed in a place that is not less than 5 times the diameter of the pipe on both sides. Note that the direction of the blade should match the direction of the water flow. The water flow indicator should be installed vertically with the pipe. If it is not installed vertically, check the flow if it is not installed vertically on the pipe to meet the requirement. When the paddle blade is installed on the pipe, the plastic blade is rolled into the pipe housing. The wiring of the flow switch of the flow indicator should be connected according to the wiring diagram. After installation, the water flow indicator should be checked and checked every six months.
