Metrology
The Core of Smart Measurement
Metrology is the foundation of Andrea Informatique’s expertise. Behind every reliable smart meter there is a metrological core designed, calibrated, and validated with scientific precision. For more than fifteen years, Andrea has supported utilities and meter manufacturers worldwide in developing metering solutions that meet the highest standards of accuracy, reliability, and compliance.
Our approach combines scientific rigor with practical experience. It starts with a deep understanding of physical measurement principles—current and voltage sensing, gas flow dynamics, or water pressure and volume—and extends to the development of sophisticated algorithms that convert these signals into traceable, certified data. Each link in the measurement chain, from the sensor to the communication interface, is modeled and tested to guarantee long-term stability and conformity with international standards such as OIML, IEC, and MID.
Metrology in Electricity
In electricity metering, Andrea designs and validates algorithms capable of capturing voltage, current, power, and energy with high precision. These metrological functions account for harmonic distortion, temperature drift, and phase imbalance to ensure consistent accuracy over time.
Our electrical metrology cores are optimized for embedded systems using low-power microcontrollers and high-resolution ADCs. They integrate seamlessly within DLMS/COSEM communication frameworks, allowing utilities to access real-time, certified measurement data. Every design follows the most demanding standards, including IEC 62053, IEC 62052, and OIML R46, guaranteeing interoperability and accuracy across global markets.
Our libraries cover single and polyphase meters.
Metrology in Gas
Gas metrology demands robustness and precision under varying conditions of temperature, pressure, and flow rate. Andrea develops algorithms and calibration methods adapted to diaphragm, turbine, and ultrasonic gas meters, ensuring stability and accuracy throughout the device’s operational life.
Our engineers focus on compensating environmental variations and validating performance over wide flow ranges, following OIML R137 and EN 1359 standards. Each meter undergoes verification of linearity, repeatability, and long-term reliability. Andrea’s metrological expertise ensures that gas metering devices meet the strictest regulatory requirements while maintaining low energy consumption and high measurement fidelity.
Metrology in Water
Water metrology presents unique challenges: low-flow detection, environmental exposure, and long-term stability. Andrea supports water meter manufacturers in optimizing the metrological chain to guarantee accurate readings over years of operation.
We develop algorithms and calibration techniques for ultrasonic and electromagnetic meters, ensuring sensitivity to minute variations in flow while minimizing drift. Our work also extends to integrating metrology functions within connected, battery-powered devices compatible with NB-IoT, LoRaWAN, or M-BUS technologies. These efforts help utilities detect leaks, monitor consumption precisely, and reduce non-revenue water losses.
Testing, Calibration & Validation
To guarantee accuracy, Andrea Informatique operates a dedicated metrology laboratory where every prototype and production sample undergoes rigorous testing. The lab performs type approval and verification testing, environmental simulations, and long-term drift analysis.
Our Phenix testing suite automates conformity and performance tests, ensuring complete traceability and reproducibility. These procedures allow us to compare multi-vendor measurement data, validate compliance with international norms, and optimize the integration of metrological functions within DLMS/COSEM environments.
