Large Diameter Ultrasonic Water Meter V16
● LCD Digits: 9
● Temperature Class: T30
● Pressure Class: MAP16
● Pressure Loss Class: △p40
● Protection level: IP68
Features
1. Dual-channel measurement, high accuracy and good stability
2. Redundancy means that even if one channel is blocked by foreign objects or an abnormality occurs, the entire meter can still measure normally.
3. With self-diagnosis function: flow sensor fault alarm, temperature sensor open circuit and short circuit alarm, measurement over-range alarm, battery undervoltage alarm ,
4. The company's patented flow measurement method (invention patent has been authorized) and intelligent data error correction technology are applied, with high measurement accuracy and stability.
5. High-definition wide temperature 9-bit LCD display
6. Built -in lithium battery power supply can ensure more than (6+1) years of use
7. Equipped with photoelectric interface, supports on-site reading with handheld infrared meter reading tools
8. Optional wired communication interface (M-BUS, RS485) or wireless communication interface (LoRa)
9. Optional built-in IoT communication module (4G or NB-IoT) to form an IoT table
10. Optional power supply modes:
1) Built-in battery power supply (default configuration)
2 ) External power supply ( used when 485 is configured, voltage range: DC (7.5 ~ 24 ) V ) ( need to be specified when ordering )
11. Counter flow can be counted
12. Optional pipeline pressure monitoring function
