Dwyer TDFS2-2-C-06 | Thermal Dispersion Flow Switch | 2 to 10" pipe, 1/2" NPT
Sized for 2 to 10" (50 to 250 mm) pipe, the Dwyer TDFS2-2-C-06 thermal dispersion flow switch has a 1/2" NPT male process connection and 6' cable with conduit connection (extended length). The TDFS2-2-C-06 shows if flow is above or below the set rate; the set point is changed in the field using the supplied magnet.
- TDFS2-2-C-06 set point range 0.5 to 10 ft/s (0.15 to 3.0 m/s)
- NO and NC NPN outputs with two LED status indicators on the TDFS2-2-C-06
- 316 SS wetted parts; TDFS2-2-C-06 rated 300 psig (20.67 bar)
- TDFS2-2-C-06 process and ambient temperature 5 to 140°F (-15 to 60°C)
- 9 to 24 VDC supply and NEMA 4X (IP65) enclosure for the TDFS2-2-C-06

- Having no paddles or vanes to wear out or break, no jams in the paddle movement, and no movement assembly seals to wear out or leak means that mechanical flow switches are less reliable and have a shorter lifespan.
- Extended lifespan due to the fact that it remains unaffected by empty pipes by preventing overheating and cooling down to the process temperature.
- Reduced pressure drop with 10% insertion into the flow (e.g., 1/8" for 3/4" schedule 40 pipe) results in a lower system run cost.
