The ultrasonic heat meter measures the flow volume and display the heat energy released or absorbed by water flow when passing though the heat exchange system.
The temperature range is 4~95ºC.
Measurement unit: Kwh, Gcal, GJ, MWh
Communication Interface choice:
1. M-BUS
2. RS-485, Modbus
3. Pulse output
4. LoRa/LoRaWAN
