1. Sanitary Flow Sensor for Precision Bioprocessing Applications
The GF Signet 721515111 is a high-purity flow sensor engineered for critical measurement in pharmaceutical and bioprocessing applications requiring EHEDG EL-Class I compliance. Featuring advanced turbine 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 for versatile installation. Designed for WFI systems, buffer transfer, and CIP return monitoring, this sensor provides pulse output and 4-20mA signals with programmable K-factors, supporting -20°C to +130°C operation with >36-month service life in aggressive chemical environments.
2. Technical Performance and Application Advantages
This flow sensor excels in mission-critical processes including WFI distribution verification (0.5-5 L/min), CIP return flow monitoring, and high-precision buffer transfer control. The device features ceramic bearing technology ensuring frictionless operation and 316L stainless steel wetted components resistant to 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 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 ideal for pharmaceutical, biotechnology, and food processing applications requiring stringent hygienic design and reliable performance.
3. Advanced Features and Regulatory Compliance
The 721515111 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 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 low-flow detection down to 0.5 L/min ensures reliable operation 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 and diagnostic capabilities for validation documentation and process management.
