This GB/T32224-2020 compliant ultrasonic heat meter features a self-developed chip and dynamic algorithm for a turndown ratio of up to 250:1. With IP68 protection, heating/cooling dual-use, over 10-year battery life, and multiple remote communication options, it is ideal for large-diameter heating systems.
1. Utilizes imported chips and high-quality transducers for accurate and stable measurement, suitable for heating and cooling metering.
2. Self-developed dedicated ultrasonic flow metering chip, multi-channel flow measurement, and dynamic integration algorithm enable low starting flow, a wide metering range, and a turndown ratio of up to 250:1.
3. Power-off memory function automatically resumes metering upon power restoration.
4. Data storage, capable of storing 24 months of historical data.
5. Remote data transmission and intelligent management options available, including M-bus, RS485, LoRa, and NB-IoT communication options. Power supply is DC12-24V and compatible with Modbus, CJ/T188, and 26831 protocols.
6. Low power consumption, battery life of over 10 years.
7. New protective design, IP68 protection rating.
8. Heat and cold metering, suitable for heating and cooling metering.
9. Complies with GB/T32224-2020, a national standard of the People’s Republic of China, for heat meters.
10. Easy installation, suitable for horizontal or vertical mounting.
