Overview
The AMAE ProFACT-E Professional Automated Flow Calibration System is an ISO/IEC 17025-aligned metrological platform engineered for high-accuracy, traceable calibration and verification of gas sampling instruments—including atmospheric samplers, dust samplers, and personal air monitoring devices. It operates on the differential pressure flow measurement principle, utilizing precision-engineered laminar flow elements and temperature/pressure-compensated dry-gas meters to deliver NIST-traceable volumetric flow readings under controlled load conditions. Designed explicitly to meet evolving Chinese national metrological standards—including updated requirements for Class C instruments (±5% flow error at 8 kPa backpressure)—the system replaces manual, operator-dependent calibration workflows with fully automated, unattended operation. Its architecture supports both pre-use and post-use calibration checks, periodic in-service verification (as mandated by CMA laboratory management protocols), and full auditability across GLP-compliant environments.
Key Features
- Fully automated, walk-away calibration sequences—no operator intervention required during flow point setting, load pressure ramping, or data acquisition.
- Integrated intelligent load pressure controller (EE-02) capable of precise, dynamic backpressure regulation from −30 kPa to +30 kPa across the full flow range (5 mL/min to 35 L/min), enabling simultaneous multi-point, multi-load testing per calibration cycle.
- Dual-mode connectivity via EE-04 Smart Interface Dock: RS-485 (for load instrument control), infrared (legacy device compatibility), dual USB-A (flow meter & PC), and Bluetooth (future OEM interoperability).
- Modular desktop integration with AMAE-DESK (EE-01): pre-wired power distribution, embedded pneumatic routing, and consolidated I/O—eliminating external cabling and minimizing setup time and contamination risk.
- ProFACT Client software with role-based access control, configurable reporting templates (PDF/CSV/XLSX), and built-in 21 CFR Part 11-compliant audit trail functionality—including user action logging, parameter change history, and electronic signature support.
- Cloud-ready architecture with optional LIMS integration via RESTful API; supports hierarchical task delegation (e.g., provincial metrology centers assigning calibrated instrument verification tasks to municipal labs with immutable test parameters and auto-uploading of results).
Sample Compatibility & Compliance
The ProFACT-E system is validated for use with all major classes of low-flow gas sampling instrumentation used in environmental monitoring, occupational hygiene, and industrial hygiene applications. It meets the technical validation criteria specified in JJG 956–2017 and JJG 1118–2015, including mandatory performance evaluation at 4.5 kPa (Class B) and 8 kPa (Class C) load pressures. All internal measurement modules—including the EE-25pro/EE-35pro smart dry-gas meters—are factory-calibrated against primary standards maintained under ISO/IEC 17025-accredited conditions. The system’s digital data chain—from sensor output through calculation engine to final report—adheres to traceability requirements outlined in CNAS-CL01:2018 and supports full documentation for CMA accreditation audits. Optional pressure transducer calibration certificates (NIST-traceable) are available upon request.
Software & Data Management
The ProFACT Client application provides a unified interface for instrument configuration, test protocol definition, real-time monitoring, and result export. Calibration protocols are stored as version-controlled XML templates, allowing laboratories to maintain standardized procedures across multiple sites. Each test generates a timestamped, digitally signed record containing raw sensor values, compensated flow calculations, load pressure profiles, uncertainty budgets (per GUM principles), and pass/fail determinations against user-defined tolerances. All records are encrypted at rest and include immutable metadata (operator ID, system firmware version, environmental conditions). Audit logs capture every configuration change, report generation event, and user login session—enabling full forensic reconstruction during regulatory inspections. Integration with enterprise LIMS is supported via HL7 or custom JSON schema mapping, with bi-directional synchronization of equipment status, calibration due dates, and certificate expiry alerts.
Applications
- Annual in-service verification of atmospheric and dust samplers in CMA-accredited laboratories.
- Pre- and post-sampling flow verification in field deployment programs governed by HJ/T 375–2007 and GBZ/T 192.1–2018.
- Factory acceptance testing (FAT) and incoming inspection of newly procured sampling instruments—validating manufacturer-stated load capability and flow stability.
- Performance evaluation of respirator fit-test systems and isolation suit integrity testers requiring precise, variable backpressure simulation.
- Method validation studies supporting ISO 16000-22, EN 12341, and US EPA Method IO-3.2 compliance.
- Remote metrological oversight in multi-tiered environmental monitoring networks—enabling provincial regulators to assign, monitor, and verify calibration compliance across distributed third-party labs.
FAQ
Does the ProFACT-E system comply with ISO/IEC 17025 requirements for calibration laboratories?
Yes—the system’s measurement uncertainty budgeting, traceability chain, and procedural documentation framework align with Clause 7.6 and Annex A of ISO/IEC 17025:2017.
Can it calibrate instruments operating outside the 5 mL/min–35 L/min range?
No—the system is validated only within this range; extension beyond requires re-validation and optional hardware upgrades.
Is remote firmware update supported?
Yes—over-the-air updates are delivered via secure HTTPS channel with SHA-256 signature verification.
How is data integrity ensured during transmission to LIMS?
All API communications use TLS 1.2+ encryption, message-level signing, and idempotent transaction handling to prevent duplication or loss.
What environmental conditions must be maintained during calibration?
Ambient temperature: 20 ± 2 °C; relative humidity: 30–70% RH; barometric pressure: 86–106 kPa—automatically compensated in real time by onboard sensors.
