The F261 Series Low-Flow Switches have 1/2 in. Female NPTF or 3/4 in. Female NPTF inlet and outlet connections.
Use F261 Low-Flow Switches in applications where flow rates are low, such as:
- Water purification and treatment systems
- Booster pumps
- Cooling systems for electronic tubes, bearings, and compressors
- In rapid recovery water heaters to start the water heater when water withdraws
- In the control of food waste disposal units to start the motor when a predetermined amount of water flow is present in the unit and to stop the motor when the flow decreases to a predetermined rate
- As a switch to shut down the refrigeration compressor on a fluid chiller system if flow stops, to reduce the chance of chiller freeze-ups
