Dwyer PFT-HDN-S611-S | Paddlewheel Flow Sensor | pulse output, 316 SS body
Part Number : PFT-HDN-S611-S
The Dwyer PFT-HDN-S611-S insertion paddlewheel flow sensor pairs a 316 SS body with a square-wave pulse output whose frequency follows flow velocity (3.2 to 200 Hz). The PFT-HDN-S611-S suits liquid flow measurement in 1-1/2 to 40" pipes over 1.2 to 25 ft/s (0.37 to 7.62 m/s).
- 316 SS body with FKM seals, tungsten-carbide shaft, PTFE bearing and 316 SS impeller on the PFT-HDN-S611-S
- 1-1/2" NPT male process connection on the PFT-HDN-S611-S
- PFT-HDN-S611-S linearity ±1.0% FS, repeatability ±0.5% FS
- Rated 400 psig (27.6 bar) at 100°F (37.8°C); PFT-HDN-S611-S temperature -40 to 212°F (-40 to 100°C)
- PFT-HDN-S611-S supply 10 to 35 VDC, NEMA 6P (IP67), 20 ft (6.1 m) cable with gland

- Long product life because of the superior wear protection provided by the bearings and shaft, even in situations with particulates.
- Use in submersible and weatherproof irrigation applications.
- Using a single unit that can be adjusted over a wide variety of pipe sizes can save time and inventory.
- Flexibility in application with an array of wetted material options.
- With an integrated 4–20 mA output, there is less need for extra peripheral components.
- Sensing technology eliminates issues about magnetic material in flow since it employs inductive sensing instead of magnets.
