Automatic Meter Reading

AMR (Automatic Meters Reading) is essential for a smart grid to take place. The country may have already deployed various meter models, either smart or dump meters, over the years. The sites could be scattered, deserted or hush. TMAS smart modems and gateways are designed to retro-fit into these environment. 

The solution can be in various approaches:

• First Approach (Dumb Meter, Smart GPRS Modem / Gateway)
  To have the quickest time to market and seamless to existing AMR software platform, TMN-51T or T61 will be the right choice as it is a truely protocol independent and transparent gateway. It has a built-in powerful 32bits ARM platform to do the low level AT command programming as such the developer or system integrator does not need to do so anymore. There is also no need to know the meter protocol as well as the API of the existing AMR software. It just works instantly after proper configuration is done.

• Second Approach (Smart Meter , Dumb Modem) :
  To have our standard RS232-Based TMAS GSM/GPRS modem, TMA-M37i or TMA-M55i Modem be the wireless utility modem for the smart electricity or energy meter. The tendering consortium partner can propose any of our available models for their own integration with the meters and desired AMR or SCADA software. AT command programming will be needed to initiate the dump modem to perform various tasks.
