Feature

●Flow switch is used for sensing changes in the flow rate of liquids flowing throuh pipes, such as water, ethylene, ethylene glycol or other non-hazardous liquids.
●The flow switch is usually used in places where interlocking or "cut-off" protection is required.
●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.
●100% brand new and high quality
●STFS-25 fully sealed liquid flow switch can use different slurry according to the flow rate of installed pipeline.

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 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 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.
