Operating Range
0.1 to 6 m/s (0.3 to 20 ft/s)
Turndown
66:1
Pipe Size
DN15 to DN900 (½ to 36 in.); PVC body DN15 to DN100 (½ to 4 in.)

Fits insertion paddlewheel sensing where you need a Type 2536 Rotor-X open-collector sensor for 0.1–6 m/s across DN15–DN900 with Signet fittings.
Key advantages
- Range — 0.1 to 6 m/s (0.3 to 20 ft/s); 66:1 turndown
- Pipe size — DN15 to DN900 (½ to 36 in.); PVC body DN15–DN100
- Output — Open collector, sinking 10 mA max; ~49 Hz per m/s
- Supply — 5 to 24 VDC ±10%, regulated; <20 mA @ 6–24 VDC
- Materials — Glass-filled PP, PVDF, or PVC; FKM O-rings
Typical applications
- Frequency input to Signet transmitters/PLCs.
- Large-pipe insertion with Signet saddles/tees.
- Lower minimum velocity than many self-powered paddlewheels.
Selection guide
- Body — PP vs PVDF vs PVC
- DN / fitting — Immersion length vs DN
- Supply — 5–24 VDC regulated
- Cable / electronics — Downstream transmitter pairing
Common mistakes
- Confusing with self-powered 515 sine output.
- PVC body above its temperature limit.
- Partially filled pipes.
When to RFQ / what to tell us
- Fluid, DN, velocity, T/P.
- Body material; fitting.
- Quantity and ship-to.
