FS-150 Series Flow Switch
Brand: Gems Sensors, IncThese slim, inline switches reduce pressure drop to a minimum.
They incorporate a unique, dual-diameter, internal bore and piston configuration to minimize flow constriction.
Liquids are able to smoothly pass around the piston and flow through the switch with little pressure loss to the down stream line.
Features- Flow Rate Settings: Liquids: 0.5 GPM to 5 GPM
- Port Size: 1/2˝ NPT
- Primary Construction Material: Polypropylene
