1100% and high quality 2Used for sensing changes in the flow rate of liquids flowing through pipes, such as water, ethylene, ethylene glycol or other non-hazardous liquids. 3When the liquid flow exceeds or falls below the set flow rate, its single-pole double-throw switch contact (SPDT) can make one circuit conduct, while cutting off the other circuit. 4The flow switch is usually used in places where interlocking or 5STFS-25 fully sealed liquid flow switch can use different slurry according to the flow rate of installed pipeline. Features:100% and high quality Used for sensing changes in the flow rate of liquids flowing through pipes, such as water, ethylene, ethylene glycol or other non-hazardous liquids. When the liquid flow exceeds or falls below the set flow rate, its single-pole double-throw switch contact (SPDT) can make one circuit conduct, while cutting off the other circuit. The flow switch is usually used in places where interlocking or "cut-off" protection is required. STFS-25 fully sealed liquid flow switch can use different slurry according to the flow rate of installed pipeline.Specification:Wide voltage:6-380VPipe fittings: 1" 11-1/2NPTMaterial of bellows and blades: phosphorous bronze and stainless steelBlade: 1", 2", 3 ", 6"Liquid temperature () : -25-120Maximum liquid pressure: (bar) : 15Installation and adjustment:1. Open the flow switch housing;2. The switch has been set at the minimum flow value when leaving the factory. Increase the flow setting value and turn the adjusting screw clockwise;3. Press the target piece to check whether the micro switch can work normally. Excessive counterclockwise rotation of the adjustment screw may lead to the failure of the flow switch;4.After the installation, please press the flow switch to check the pulp bar several times. One , there is no "click" sound when the pulp bar returns.Turn adjusting screw clockwise until there is a "click" sound;5.The adjustment screw of black lacquer seal is only for factory to adjust the flow switch state, please do not change or adjust it;6. Observe three working cycles, make sure that the switch and the system connected with it are in normal operation, and cover the switch shell in time.Package list:1 x liquid flow switch1 x Chinese and English manual4 x target piece
