Ultrasonic Water Meter
The ultrasonic water meter is a new type of water meter that performs flow measurement and display based on the ultrasonic time-difference principle.
The meter is equipped with an M-BUS interface by default. It can form a remote meter reading management system with other communication devices through the M-BUS bus. The management department can copy data from the meter at any time, facilitating the statistics and management of users' water consumption.The product implements the standard GB/T 778 Measurement of Water Flow in Closed Full Pipes - Cold Water Meters and Hot Water Meters for Drinking Water and the verification regulation JJG 162-2009 Cold Water Meters.
Features:
1. Dual-channel measurement, with high accuracy and good stability.
2. Redundancy: Even if one channel is blocked by foreign objects or malfunctions, the entire meter can still measure normally.
3. Self-diagnosis function: Flow sensor fault alarm, temperature sensor open-circuit and short-circuit alarm, over-range measurement alarm, battery under-voltage alarm.
4. Applies flow measurement methods and intelligent data error correction technology, resulting in high measurement accuracy and stability.
5. High-definition wide-temperature 9-digit LCD display.
6. One lithium battery can ensure a service life of more than 6+1 years.
7. Equipped with a photoelectric interface, supporting on-site reading by handheld infrared meter reading tools.
8. Optional wired communication interfaces (M-BUS, 485) or wireless communication interface (LoRa).
9. Optional built-in IoT communication module (GPRS or NB-IoT) to form an IoT meter.
10. Optional power supply methods:
1). Built-in battery power supply (default)
2). M-BUS power extraction
3). External power supply (DC 7.5~24V)
11. Bidirectional metering (forward and reverse metering) is available.
