| Manufacturer | Georg Fischer (GF) Piping Systems |
| Product Line | Signet 2550 |
| Model Number | 300160084 (Signet 2551 Basic Sensor, 3/4" NPT Thread, 2-100 L/min) |
| Product Type | In-line Paddlewheel Flow Sensor / Flow Meter |
| Primary Function | Measures the flow rate of conductive and non-conductive liquids using a free-spinning paddlewheel rotor. Provides a raw frequency output signal proportional to flow rate. |
| Flow Range (Water) | 2 to 100 liters per minute (L/min) [Approx. 0.5 to 26.4 US Gallons per minute (GPM)] |
| Pipe Size Connection | 3/4" NPT (National Pipe Taper) internal thread |
| Accuracy | ±2% of reading, repeatability ±0.5% (for water, under steady flow conditions) |
| K-Factor (Pulses per Liter) | Programmable (Typically calibrated at factory) |
| Output Signal | Passive, 2-Wire Frequency Signal. The spinning rotor generates a sine wave signal whose frequency is proportional to flow rate. Requires a separate Signet converter or transmitter (e.g., 2550, 2850) for signal processing and display. |
| Maximum Output | 2.5 V peak-to-peak (into a 10 kΩ load) |
| Wetted Materials | Rotor & Shaft: PVDF (Polyvinylidene Fluoride) Body & Paddlewheel: PP (Polypropylene) O-Rings: EPDM (Standard) |
| Pressure Rating | 10 bar (145 psi) @ 23°C (73°F) 5 bar (72.5 psi) @ 80°C (176°F) |
| Media Temperature Range | -20°C to 80°C (-4°F to 176°F) [Standard with EPDM O-rings] |
| Minimum Conductivity | Not Required. Suitable for both conductive (water) and non-conductive (deionized water, solvents, oils) liquids. |
| Installation | In-line. Requires a minimum of 10 pipe diameters of straight pipe upstream and 5 downstream for optimal accuracy. |
| Key Differentiator | This model is designed for smaller pipe sizes (3/4") and a lower flow range compared to other models in the 2551 series, making it ideal for applications with lower flow rates. |
| Chemical Resistance | Excellent resistance to a wide range of acids, bases, and solvents due to its all-thermoplastic (PP/PVDF) wetted construction. |
| Compatible Electronics | Signet 2550 Flow Rate Transmitter, Signet 2850 Multi-Parameter Controller, Signet 9500 Transmitter, or any PLC/processor with a frequency input card. |
| Typical Applications | Chemical dosing, skid-mounted equipment, solvent blending, low-flow cooling circuits, and laboratory water treatment systems. |
