The FSW-140 Series rugged
inline flow switches offer superior
performance. Their fixed set-point
and simple design make it a
dependable switch. This series is
an ideal choice for coolant
applications requiring reliable flow
detection in HVAC, semiconductor,
welding, medical and other
industries. The ¹⁄₄" quick disconnect
units have a host of snap-on mating
adaptors available to fit most
piping requirements.
