This Smart Water Meter can be integrated with software to achieve versatile functions such as remote meter reading, management, and prepaid services etc.
It is easily implemented in networking, and supports various wireless communication methods (such as LoRaWAN, NB-IoT, GPRS, RS485, etc.), This water meter is advantaged by lower power consumption, massive connectivity, and reliable data transmission.
It can be wildly utilized in multiple applications like residential, hotel, modern apartment, smart city, smart water management, and smart community scenarios for water flow measurement and energy management.
Features
- There are no moving parts in the ultrasonic water meter body, whether mechanical wear or measurement accuracy both can be maintained for a long time.
- A large range ratio and a small initial flow rate, and very small starting flow.
- The measurement accuracy is after operation, but factory inspection can be required according to Class 1 accuracy standard.
- Fluid temperature changes, and can achieve T30/T50/T70 temperature grade.
- Strong anti-static(more than 12000V) and anti-magnetic interference capabilities.
- Adopts micro-power consumption design technology to minimize the comprehensive power consumption of the water meter and has a service life of more than 6 +2 years.
- Select multiple communication modes(NB-IOT LoRa, LoRaWAN, M-Bus. RS485, pulse and other communications)
- Long-term data storage.
- Water flow direction recognition mechanism, which can measure the positive and negative flow.
- Long time water running (leakage alarm) alarm mechanism and an oath reporting mechanism.
- Empty pipe alarm mechanism, which can be used as an abnormal disassembly alarm after a long period of normal water running.
- Judgment mechanism of false counting (instantaneous excessive flow metering).
- Metering the fluid temperature, and can give low or high temperature alarm.
- Domestic water care mechanism.
- Valve control function.
