SL-15SFD Liquid Flow Switch
liquid flow switch is designed for managing the flow changes when the liquid flows in the pipe, such as water, ethylene glycol or other non-hazardous liquids. When the liquid flow is higher or lower than the setting value, the single-pole double- throw contacts (SPDT) can get through one circuit and at meantime to break the other circuit. FS series liquid flow switch is commonly used for chain reaction or “no flow” protection.

Application
The typically application is used to protect the cooling system, when the cooling water is off, FS flow switch can shut off thecompressorcurrent efficiently in order to protect the freezer and entire system from being damaged.

1. Above flow values are for the reference of choice
2. The figures with “ * ” symbol are for the 4 paddles flow switch. While, the figures without “ * ” symbol are for the 3 paddles (1, 2, 3 ) flow switch.
3. The paddles will be chose according to the flow in the main pipe where the flow switch is installed in.
