The mechanical 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
Communication Interface choice:
1. M-BUS
2. RS-485
3. Pulse output
4. LoRa/LoRaWAN
5. Water Meter Impulse output, connects Heat Meter, M-BUS/RS-485 output
