Three Phase LoRaWAN WattHour Meter
Introduction:
DTS150 series FBR(LoRaWAN) three phase four wire electric energy meter adopts advanced SMT production design and manufacture. Besides measure active energy, it also has function for online power display, smart anti-tamper, overload control, remote meter reading and etc. It sends data to corresponding gateway through LoRaWAN wireless network. It has advantages in high accuracy, low power consumption, and good stability that can be widely used for the single phase alternating current in city, rural areas or factory enterprises, etc.
