Fits full-pipe liquid flow sensing where you need a GF Signet 515 Rotor-X self-powered paddlewheel frequency sensor for DN15–DN900 with Signet installation fittings.

Key advantages

  • Range — 0.3 to 6 m/s (1 to 20 ft/s); pipes DN15–DN900 (½–36 in.)
  • Output — Self-powered sinusoidal AC frequency (~19.7 Hz per m/s); no external power
  • Accuracy — Linearity ±1% of max range @ 25 °C; repeatability ±0.5%
  • Materials — Glass-filled PP or PVDF body; PVDF/ETFE rotor; multiple shaft options
  • Install — Signet fittings (tees, saddles, weldolets); wet-tap with Type 3519

Typical applications

  • Water and compatible chemical flows in plastic or metal pipes with Signet fittings.
  • Simple frequency input to Signet transmitters/controllers.
  • Wet-tap maintenance installations with Type 3519.

Selection guide

  • Body — PP vs PVDF for temperature/chemistry
  • Fitting / DN — Tee/saddle/weldolet; immersion length
  • Shaft / O-ring — Ti/Hastelloy/ceramic/SS/Ta; FKM/EPDM/FFKM
  • Cable — 7.6 m standard; extendable to 60 m max

Common mistakes

  • Using below minimum Reynolds (~4500) or on partially filled pipes.
  • Mismatched fitting DN vs sensor immersion length.
  • Expecting 4–20 mA directly from 515 — it is a frequency sensor.

When to RFQ / what to tell us

  1. Fluid, DN, velocity min/max, T/P.
  2. Body/shaft/O-ring; fitting type.
  3. Quantity and ship-to.
