Q: Can the data collector DTU panel directly reflect the current working state of the device?

A: Yes, there are three status indicators on the collector panel, namely the network status indicator, the platform server connection status indicator and the meter data reading indicator. 

Q: Can the DTU collect metering data in the gas meter or water meter?

A: Yes, it is compatible with modbus gas or water meters.

Q: When the network is abnormal, will the data be lost?

A: No, we designed a memory chip that can store 2-12 months’ meter data.

Q: Do you have APP for the data collector. The DTU/RTU?

A: Since different areas' clients have different using habit, so APP is always customized for clients according to the developing instructions clients give.

Q: Can you put our logo on the smart energy meter, DTU and software?

A: Yes, we can put your logo on the meter, data collector(concentrator) and system software.
