GF Signet 721250115 Flow Sensor 4-20mA Output 150PSI NEMA 4X

1. Sanitary Flow Sensor for Precision Bioprocessing​

The GF Signet 721250115 is an advanced sanitary flow sensor engineered for critical measurement applications in pharmaceutical and bioprocessing industries. Featuring turbine-based technology with ceramic bearings and 316L stainless steel construction, this device delivers ±0.5% accuracy across 0.5-60 L/min ranges with ≤80ms response time. Its IP69K-rated housing withstands 150°C SIP cycles and 100-bar CIP cleaning while meeting ASME BPE-2022 standards with Ra≤0.4µm surface finish. The sensor incorporates integrated temperature compensation and bidirectional flow detection capabilities, supporting versatile installation configurations. Designed for WFI systems and buffer transfer applications, it provides 4-20mA and pulse outputs with programmable K-factors, ensuring reliable operation from -20°C to +130°C with >36-month service life in aggressive chemical environments.

​2. Technical Performance and Application Advantages​

This precision flow sensor excels in critical bioprocessing applications including WFI distribution verification (0.5-5 L/min), CIP return monitoring, and high-accuracy buffer transfer control. The device incorporates ceramic bearing technology that ensures frictionless operation and 316L stainless steel wetted components that resist corrosive cleaners and sterilizing agents. Its ultra-smooth surface finish (Ra≤0.4 µm) prevents biofilm accumulation while the bidirectional flow capability enables flexible installation without directional constraints. The integrated temperature compensation system maintains accuracy across 0-100°C fluid temperatures, and quick-disconnect tri-clamp fittings facilitate rapid installation and optimal cleanability. Compliant with FDA 21 CFR 177.2600 and EHEDG standards, this sensor is ideally suited for pharmaceutical, biotechnology, and food processing applications requiring stringent hygienic design and reliable performance.

​3. Advanced Features and Regulatory Compliance​

The 721250115 utilizes a free-wheeling turbine with optical sensor detection, providing high-resolution flow measurement with 100 pulses per revolution. The hygienic design meets EHEDG Class I criteria through crevice-free construction, self-draining orientation, and steam-sterilizable components supporting SIP cycles up to 150°C. Comprehensive regulatory compliance includes 3-A Symbol 74-03, FDA 21 CFR 177.2600 materials registration, and EC1935/2004 for food contact applications. The programmable K-factor allows customization for various fluids, while sophisticated low-flow detection ensures reliable operation down to 0.5 L/min across all process conditions. ATEX Zone 2 certification enables safe deployment in hazardous areas with flammable solvents, while integrated HART communication provides comprehensive remote configuration, monitoring, and diagnostic capabilities for validation documentation and automated process management.
