Fits full-pipe liquid flow sensing where you need a GF Signet 2536 Rotor-X open-collector paddlewheel sensor for 0.1–6 m/s with 5–24 VDC supply and Signet fittings.

Key advantages

  • Range — 0.1 to 6 m/s (0.3 to 20 ft/s); DN15–DN900 (PVC body DN15–DN100)
  • Output — Open collector, sinking 10 mA max; ~49 Hz per m/s
  • Supply — 5 to 24 VDC ±10%, regulated
  • Performance — Linearity ±1% / repeatability ±0.5% of max range @ 25 °C; 66:1 turndown
  • Materials — PP, PVDF or PVC body; PVDF rotor; FKM O-rings (EPDM/FFKM opt.)

Typical applications

  • PLC/discrete frequency inputs needing open-collector paddlewheel signals.
  • Lower-velocity flows than 515’s 0.3 m/s minimum.
  • Signet fitting installs across DN15–DN900.

Selection guide

  • Body — PP vs PVDF vs PVC (PVC temp 0–50 °C)
  • DN / fitting — Match immersion length
  • Supply / input type — 5–24 VDC open-collector sinking
  • Cable — 7.6 m standard; extendable to 305 m

Common mistakes

  • Confusing 2536 (powered open-collector) with 515 (self-powered sine).
  • Using PVC body above 50 °C.
  • Partially filled pipe installs.
