Features
1.Uses picosecond-level high-precision metering chips, providing low starting flow, wide measurement range, high accuracy, and the ability to measure even the smallest drops of water.
2.The electronic components are fully sealed, offering waterproof, moisture-proof, dust-proof, dirt-proof, and sand-proof characteristics.
3.Can store 24 monthly records, 360 daily records, and 192 hourly records. Data can be preserved for a long time even after power loss.
4.Real-time monitoring of battery, temperature, and flow. In case of low battery voltage, transducer abnormalities, or non-full pipe (empty pipe) conditions, the system has the capability to detect, record, and alert. The screen will display corresponding prompts.
5.Multiple communication options are available (infrared, RS-485, M-Bus, NB-IoT, LoRa, Cat1, TTL, LoRaWAN, etc.) to enable centralized meter reading, parameter setting, and other functions.
6.Optional valve control function for remote valve operation.
7.Supports remote online upgrades at the meter end, continuously meeting new requirements for the water meter and addressing user concerns.
