CFS150 Series Piston Type Switch

Low Pressure Drop, Liquid Flow rates from 0.5 GPM to 5 GPM

DESCRIPTION

These 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.

Notes:
1) Flow settings are calibrated using water @ +70°F on increasing flow, 
     with units in a horizontal position (terminals up).
2) Care should be taken by specifiers to ensure fluid compatibility with 
     the above listed wetted materials.
3) Use of 150 micron filtration is recommended.
