GSM/GPRS Modems For AMR Solutions

Web based Remote GSM/GPRS Based Wireless AMR Solutions:

We Graphite basically offer total web based AMR (Automatic Meter Reading) solutions to get data from remote Devices/ instruments such as Energy meter, Water meter, Gas meter,Solar Energy panels,Wind Energy Panels or any type of instrument with RS485 or RS232 ports. With the help of this AMR solutions you can get the data for study on a Graphite’s central server for live Real Time monitoring, and analysis. GPRS/GSM MODBUS RTUs.

The PLCs are generally getting used in System integrations by system integrators in automations of various machines ,water treatment plants, systems and projects. It happens that many a times the data has to be communicated from any remote location to a central control room. So to do this the PLCs are get programmed to send data on a RS232 port or RS485 port i.e., MODBUS communication. With the help of a GSM/GPRS enabled RS232 RTU at the PLC you can get all required data from the PLC to the Graphites central server.When there is a requirement of multiple PLCs and instruments and their data is to be sent to a central control room then at that time you can use RS485 MODBUS RTU. Graphite can connect all the PLCs and instruments on the common BUS of RS485 MODBUS RTU. This data will be then sent to Graphites central server one by one. Each PLC will be assigned with a unique ID in software so that when the RS485 MODBUS RTU is taking data from each individual PLC that will not get mixed and is separated on the basis on ID of the respective PLC.

In many Industrial machines the GSM/GPRS enabled RS232 RTUs and RS485 MODBUS RTUs are being used at the manufacturing stage only. This helps when the machines gets sold out and got installed at client site, its operational real time data can be monitored by the any authority who is having respective link & User Id,Password along with the manufacturer at its central control room for live monitoring, study and analysis.This assists & give an opportunity to be proactive in protecting the machine against abnormal failures, identification of correct time of maintenance, time & fault management.

We Graphite is a manufacturer OEM modules of GSM/GPRS enabled RS232 RTUs and RS485 MODBUS RTUs for such applications.These are our products can be used in air compressors,industrial water filters, solar inverters, UPS, transformers, lath machines, any of the production lines, in boiler management, furnaces, hydraulic presses, cooling towers, air conditioning plants for AHUs, elevators, food processors, electric motors,Diesel Generators & many places.

The Devices, instruments like Energy meters, flow meters, pressure transducers, level sensors can also be connected to GSM/GPRS enabled RS232 RTU and RS485 MODBUS RTU for getting the data from any remote locations to a central server. Graphite’s GSM/GPRS enabled RS232 RTU and RS485 MODBUS RTU can be used for or AMR solutions and applications


Our Graphite’s RTUs have a built in modem for wireless data communication. Data at the field Devices/ instruments/Sensors are available at RS232 port or RS485 port. Our RTU gets the data from these ports and sends it to a microcontroller for processing. This processed data is then sent to GSM/GPRS modem for transmission to the Graphite’s remote central server. As soon as the data gets received at the remote server at a assigned port and then gets stored for further processing.
