CFS4 Piston Type Flow Switch
Liquids from 0.1 to 1.5 GPM, Ryton® Construction
DESCRIPTION
The CFS-4 Series makes flow protection economical for a broad range of industrial applications such as welders, lubrication systems, medical sterilizers and chemical dispensing.
A piston, encapsulating a permanent magnet, is positioned in the flow path within the unit housing. When displaced by the pressure differential from fluid flow, this piston magnetically actuates a hermetically sealed reed switch (SPST or SPDT, depending on the part number) within the unit.
