CFS200 Series Shuttle Type Flow Switch

Low Pressure Drop, Liquid Flow Set Points from 0.5 GPM to 100 GPM

DESCRIPTION

The CFS200 Series offers accurate flow detection, with 1% repeatability, over a broad range of flow settings and port sizes. Its durable construction delivers long-life reliability in either water or oil. Generous flow paths keep pressure drop low. These switches are ideal for detection of improper flow rates in high volume lubrication, cooling or process systems.

CFS-200 Adjustable Series switches offer the same accuracy and are as rugged as those with fixed settings, but provide one additional feature: external adjustability. With these versatile switches your choice of flow settings is diverse within a given range. An ordinary, flat-blade screwdriver is all that's required for the actuation adjustment.

Approved for Class I, Division 2, Groups A, B, C, D hazardous areas. Shuttle Type Flow Switch Operation As liquid flow increases to the actuation setting, a magnet-equipped shuttle is displaced. When displaced by fluid flow, this shuttle actuates a hermetically sealed, SPDT or SPST reed switch within the unit stem. A compression spring or gravity provides shuttle return when flow decreases. Adjustable versions of the CFS200 incorporate an internal adjustable bypass vane which is controlled externally using an ordinary, flat-blade screwdriver.

Notes: 1) Flow settings for fixed versions are calibrated using water at +70°F on increasing flow, with units in a horizontal position (lead wires up). Consult us regarding special flow setting calibration, or liquids other than water. Temperature changes will slightly affect the flow settings listed. Oil flow settings will vary with viscosity. 2) Adjustable units that are set to customer specification are subject to factory test stand accuracy. 3) Use of 150 micron filtration is recommended. 4) Minimum 5 PSI line pressure required.
