Key parameters
Measuring range
0.3 to 6 m/s (1 to 20 ft/s); pipe sizes DN15–DN900 (½–36 in.)
Accuracy
Linearity ±1% of max range @ 25 °C; repeatability ±0.5% of max range @ 25 °C
Output
Self-powered sinusoidal AC frequency ~19.7 Hz per m/s (6 Hz per ft/s); amplitude ~3.3 V p-p per m/s
Supply
None (self-powered / no external power required)
Process connection
GF Signet installation fittings (tees, saddles, weldolets); wet-tap with Type 3519
Wetted parts
Body glass-filled PP or PVDF; O-rings FKM (EPDM/FFKM opt.); rotor PVDF/ETFE; shaft Ti/Hastelloy-C/PVDF/ceramic/SS/Ta options
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
- Fluid, DN, velocity min/max, T/P.
- Body/shaft/O-ring; fitting type.
- Quantity and ship-to.
