+GF+ 3-2537-5C-P0 - Flow-Sense / Signal-Out - Precise Compact Flow Transmitter

Next‑Generation Digital Paddlewheel Flowmeter for ½–4″ Process Lines

The +GF+ Signet 3‑2537‑5C‑P0​ is a next‑generation integral‑mount paddlewheel flowmeter​ designed for continuous liquid‑flow measurement in industrial automation loops. The ‑P0​ material set specifies a glass‑filled polypropylene body, black PVDF rotor, titanium pin, and FKM (Viton) O‑rings​ for solid chemical resistance at a cost‑effective price point. Key parameters: flow range 0.1–6 m/s (0.3–20 ft/s), linearity ±1% FS, repeatability ±0.5% FS, minimum Reynolds 4500, and a 100 ms​ system response time. The "5" output code​ delivers a native Digital (S³L — Serial Sensor Link)​ signal that connects directly to Signet 8900 multi‑parameter controllers​ (up to six 2537 sensors on one bus), 9900, or 9950​ transmitters without extra signal conditioning.

Where It's Used, Core Automation Function & Advantages

Its core function is to provide a high‑resolution, digitally noise‑immune flow signal​ so the control layer can execute pump‑protection interlocks, flow‑proportional dosing, filtration monitoring, tank‑fill logic, and totalized batch accounting—always for conductive or non‑conductive full‑pipe liquids​ (no minimum conductivity requirement, unlike magmeters). Typical deployments include chemical processing, water/wastewater monitoring, RO/DI make‑up, scrubber recirculation, cooling‑tower bleed, and metal‑finishing rinse loops. Advantages are the S³L digital link​ (long cable runs with no analog drift), onboard local UI/LCD​ for K‑factor setup and calibration without a laptop, NEMA 4X/IP65​ field‑mountability, and drop‑in compatibility with existing Signet 515/2536 tee, saddle, and weld‑on fittings—making retrofits fast and spares lean.

The +GF+ Signet 3-2537-5C-P0 is an integral mount paddlewheel flow sensor for use in pipes sized DN15 to DN100 (½″ to 4″). Constructed with a Polypropylene body, a black PVDF rotor, and a Titanium pin, it is compatible with a wide range of industrial fluids. This model is distinguished by its Digital (S³L) communication output, which supports a multi-function mode capable of providing flow rate, total flow, and flow switch signals, allowing up to six sensors to be connected to a Signet 8900 controller.
