What is the historical data storage capacity and backup solution for radar level meters?

Radar level meter historical data storage employs a dual local + cloud storage architecture ensuring data security and long-term preservation. The storage solution includes:

• Local Storage: EC32/EC60 RTU built-in high-capacity storage retains 1-2 years of measurement data with offline data continuation capability
• Cloud Storage: Real-time upload via 4G networks to cloud servers with permanent data retention supporting 10+ years of historical queries
• Data Compression: Advanced compression algorithms reduce storage space by over 60%
• Automatic Backup: Daily automatic backup to multiple server nodes ensuring 99.9% data reliability

The visual radar level meter supports multiple data export formats (Excel, CSV, PDF) facilitating user data analysis and report generation. The system provides API interfaces for seamless integration with third-party water management systems. Historical data serves hydrological analysis, flood forecasting, and water resource management applications, providing reliable data support for scientific decision-making.
