FS series liquid flow switch is commonly used for chain reaction or “no flow” protection. It is designed to protect the cooling system by 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 the same time break the other circuit. When the cooling water is off, the FS flow switch can shut off the compressor current efficiently in order to prevent the freezer and entire system from being damaged.
