product features
1. Utilizing 4G network communication technology, direct connection is established via the UDP protocol without requiring relay through carrier platforms. 4G base stations are widely distributed and numerous, featuring minimal coverage blind spots and high transmission speeds.
2. Adopted low-power design with daily average power consumption not exceeding 30 μA and battery life ≥6 years
3. This water meter features Bluetooth functionality, enabling batch switching for valve production testing and facilitating on-site after-sales service maintenance.
4. The water meter supports one-time reporting of 7-day frozen data: It features the capability to store 7-day historical frozen data and provides a comprehensive report covering the entire period.
5. This water meter can store historical data of 96-point curves daily.
6. Water meter data can be submitted in batches within a predefined period (configurable from 1 to 7 days). By default, reports are generated every 2 hours (completing every 2 days), but the submission frequency can be adjusted to intervals ranging from 30 minutes to 6 hours, until the user completes payment and activates the valve.
7. The water meter can be configured with periodic reporting functions (daily, weekly, monthly, or yearly) and report cycles. You can also set the reporting time to a fixed daily schedule.
8. Supports 4G remote upgrade functionality.
