DTS 307 is a Revenue Grade Meter (RGM) that can connect to Tigo's Cloud Connect (CC) or Cloud Connect Advanced (CCA). Other DTS meters from Measurlogic can connect to the CC/CCA as long as they are equipped with Modbus RTU RS-485 communication protocol. Meters sold separately by Measurlogic. Those models include:
- DTS 307
