Design considerations
- Ultra-low-power operation and battery lifetime management are critical to sustaining maintenance-free operation lifteimes, requiring highly efficient power conversion, battery monitoring, intelligent power distribution and support for energy harvesting in select applications.
- Accurate flow measurement is essential for billing and resource management, leveraging ultrasonic sensing technologies and low-noise analog signal conditioning to maintain measurement accuracy across varying flow rates and environmental conditions.
- Reliable communications and connectivity enable secure transfer of consumption data through low-power wireless networks to nearby gateways or data concentrators, while supporting wired interfaces such as M-Bus for industrial and commercial installations.
- Data security and meter integrity require hardware-based protection of measurement data, device credentials and cryptographic keys, using secure elements and robust authentication mechanisms to prevent tampering, cloning, unauthorized access and fraudulent billing activity.
- Robust operation in harsh environments is necessary to ensure long-term reliability despite temperature extremes, humidity, vibration, water exposure and other environmental stresses encountered in field deployments.
