Paddle Wheel Safety Flow Switch for Accurate Flow Control and Chemical Safety
The Paddle Wheel Safety Flow Switch (PWFS) is designed to prevent accidental chemical feeding in bypass lines. It features a visual flow indicator with high-visibility rotors and solid-state electronics housed in a compact, panel-mounted unit. This switch ensures accurate flow rate output while providing immediate visual confirmation of flow.
Typical Applications:
- Water purification
- Chemical metering
- Lasers and welders
- Water injection systems
- Semiconductor processing
- Chillers or heat exchangers
