Key parameters
Measuring range
0.1 to 6 m/s (0.3 to 20 ft/s)
Output
Multi-function pulse / flow switch; Digital (S3L); or 4–20 mA
Supply
S3L 5.0–6.5 VDC; 4–20 mA loop-powered options per datasheet
Wetted parts
PP or PVDF sensor body; FKM O-rings; PVDF rotor
Mounting
Integral mount paddlewheel flowmeter
Pipe Size Range
DN15 to DN200 (½ to 8 in.)
Fits integral paddlewheel metering where you need a GF Signet 2537 with pulse/flow-switch, S3L digital, or 4–20 mA outputs for DN15–DN200 pipes.
Key advantages
- Range — 0.1 to 6 m/s (0.3 to 20 ft/s); DN15 to DN200 (½ to 8 in.)
- Outputs — Multi-function pulse / flow switch; Digital (S3L); or 4–20 mA
- Performance — Linearity ±1%; repeatability ±0.5% of max range @ 25 °C
- Materials — PP or PVDF sensor body; FKM O-rings; PVDF rotor
- Compatibility — GF 9900 / 9950 transmitters (S3L)
Typical applications
- Compact integral flow points on small-to-medium pipes.
- S3L digital loops into GF 9900/9950.
- Low-flow / low-power operating modes.
Selection guide
- Output — Pulse/switch vs S3L vs 4–20 mA
- Body — PP vs PVDF
- Pipe DN — DN15–DN200 with matching fitting
- Supply — S3L 5.0–6.5 VDC vs loop-powered mA options
Common mistakes
- Ordering 2537 for DN900 lines — size stops at DN200.
- Mismatched S3L vs 4–20 mA transmitter expectations.
- Partially filled pipe installs.
When to RFQ / what to tell us
- DN, fluid, T/P, velocity.
- Output type and body material.
- Quantity and ship-to.
