Flow switch, FQS (061H4005)
Code: 061H4005Product detailed description
The Danfoss FQS flow switch monitors liquid flow in a pipe and automatically switches an electrical circuit when the flow drops below or exceeds a set value. It is typically used to protect pumps, boilers and cooling circuits against operation without sufficient media flow.
- Type designation: FQS-W30G
- Pipe diameter range: 25–150 mm (DN25–DN150)
- Max. flow velocity: 2 m/s
- Suitable media: Fresh water, Glycol, Neutral brine
- Media temperature range: 5 to 80 °C
- Process connection: R 1 in (threaded)
- Max. working pressure: 10 bar
- Contact function: SPDT
- Housing design: waterproof
- Enclosure rating: IP42
- Ambient temperature range: -25 to 80 °C
- Approvals: CE
