Used for sensing changes in the flow rate of liquids flowing through pipes, such as water, ethylene, 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:6-380V
Pipe fittings: 1" 11-1/2NPT
Material of bellows and blades: phosphorous bronze and stainless steel
Blade: 1", 2", 3 ", 6"
Liquid temperature () : -25-120
Maximum liquid pressure: (bar) : 15
Installation 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 to the failure of the flow switch;
4. After the installation, please press the flow switch to check the pulp bar several times. One day, 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.
