CFS10798 Series Adjustable Piston Type Flow Switch

Water, Oil & Gases, Liquid Flow Rates 0.5 to 20 GPM, Gases from 1 to 100 SCFM

DESCRIPTION

These externally adjustable switches are ideal for protecting machine tools from coolant flow failure, for protecting bearings from loss of lubricant or to assure proper air flow.

They offer an infinite number of flow settings at pressures up to 1000 PSIG, with low pressure drop and precise repeatability. The adjusting vane is easily field adjustable using an ordinary flat-bladed screwdriver. The adjustment is set-screw-locked for tamper-free operation after field calibration.

SPECIFICATIONS

Adjustable Flow Setting Range:
     Liquids: 0.5 to 20 GPM
     Gases (Min. 5 PSI Line Pressure):
          For 5 PSIG Line: 1 to 75 SCFM Approx.
          For 100 PSIG Line: 3 to 160 SCFM Approx.


 

  
Water or oil flow units should not be utilized for air/gas applications. 
The CFS10798 Gas Flow configuration utilizes a special dash-pot
piston for reliability. The flow adjustment ranges are
typical for air service. For other gases,
the flow range will vary with the density 
of the gas.

Groups A, B, C, D hazardous locations.
Adjustable Piston Type Flow Switch Operation
An externally rotatable vane is positioned in the main flow path 
within the unit. The magnet carrier piston is located in a bypass 
flow chamber. Pressure differential, caused by flow around the 
adjusting vane, displaces the spring-biased piston which actuates 
a hermetically sealed SPDT reed switch within the unit.
