Calibration Technician
Extract flow rate telemetry from open62541 OPC UA client sessions and compare with reference meter logs.
Calculate percentage measurement deviation across multiple flow velocity setpoints.
Flag flowmeters showing systematic gain error or zero-point offset drift.
Generate a standardized calibration bench test ticket with recommended span adjustments.
Calibration test bench interface displaying error curves and bench work orders.
Synthesize JSON records of open62541 OPC UA flow transmitter nodes and calibration lab master meter values. Starter examples below are synthetic. They are not downloaded records.
open62541 OPC UA Utilizes open62541 OPC UA client and server information models and data types from Source 0.
pydantic-ai, matplotlib. Pydantic AI ensures type-safe validation of metrology curves and generates structured technician instructions. Local or hosted LLM to compose calibration deviation narratives and technician recommendations.
Submit runnable source, pinned dependencies, setup commands, a working interface, example outputs, and a recorded end-to-end demo. Include tests and an action log.
Identifies meter drift exceeding ±0.5% of reading.
Calculates required zero and span calibration adjustment coefficients.
Emits compliant calibration bench dispatch records.
