M-200 Adjustable Flow Switch
Brand: MalemaThe M-200 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.
Features- Field adjustable - Infinite flow range
- High repeatability
- Extremely sensitive
- Minimum pressure drop
- Position insensitive
