Feature: It is used to measure the dynamic state of the liquid flowing through the pipeline, such as: water, ethylene, ethylene glycol and other liquids that have no corrosive effect on copper. When the flow rate of liquid exceeds or falls below the set flow rate, the SPDT contacts can turn on one circuit and cut off the other at the same time. The flow switch is usually used in places requiring interlocking or cut-off protection. Repeatability error is about 2.5%, ensure high stability of products. IP54 protection level, more safer to use. Perfect for water treatment system, central air conditioning, water cooling unit.

Open the flow switch2. The switch has been set at minimum flow rate. Turn the adjusting screw counterclockwise to increase the flow setting value.3. Press the target to check whether the micro switch can work normally. Excessive clockwise rotation of the adjusting screw may lead to the failure of the flow switch.4. After the installation, please press the lever of the flow switch several times to check. If there is no click sound, turn the adjusting screw counterclockwise until there is click sound.5. The adjustment screw of lacquer seal is only used for the first time to adjust the state of flow switch. Please do not change or adjust it.6. Observe three oper
