Adjustable Flow Switches
M-201-T Series
High flow,
adjustable flow switch
with right-angle flow
Features
• Field adjustable -- infinite flow range
• High repeatability
• Extremely sensitive
• Minimum pressure drop
• Position insensitive
Applications
• Cleaning Tools in the semiconductor industry
• Cooling systems
• Water treatment systems
• Process flows
The M-201-T Series flow switches are engineered and field tested
for sensing increasing and decreasing flow rates of gases or
liquids. Pressure variation effects are minimal. This series features
such versatility, economy, and accuracy that they can be used in
virtually any application requiring fool-proof inexpensive flow
detection.

Operation
The flow switch is activated by flow forcing a piston kept in
place by a spring to travel past a reed switch. This provides a
positive signal after a certain amount of travel. Set point
adjustment is controlled by adjusting the positioning of the reed
switch.
* Maximum flows through switch are higher.
For higher flow settings, contact factory.
