Non-Adjustable Flow Switches
The M-80 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. (The M-80 Series is manufactured under license from
CT Platon Ltd., United Kingdom.)
