Note: 1. It is absolutely forbidden to impact the key on the switch motherboard, which will lead to deformation and failure of the flow switch. 2.When wiring or debugging, cut off the power supply. 3. When performing wiring, it is absolutely forbidden to adjust any screws other than micro switch terminals and grounding screws. And connecting the wire carefully.
Application: This product is used to measure fluid dynamics of fluids passing through pipes such as water, ethylene thinners, glycols and other liquids that do not corrode copper.
Safe & Long Service Life - Adjustable flow control value and stable action point. IP54 protection class, micro-switch contact life up to 100,000 times.
Suitable for: The water flow switch is suitable for water treatment systems, central air conditioning, water cooling equipment.Place of use: Flow switches are normally used in places that require interlocking or "cutting" protection.When the flow exceeds the set value, the fluid drives the blades and the micro switch, and the SPDT contact can connect the circuit and disconnect other circuits.
4.Special grounding screws must be used for wiring, and the installation screws cannot be removed. 5. The blade of the flow switch cannot contact the inner wall of the pipe and other regulating valves in the pipe.
