SANDS make of AMR Modem SAM-1101 is a smart electric meter reading device that can be connected to any make of electronic energy meter by means of an optical/ RS232 port, which is compliant with DLMS IEC 62056-21 standard. The electric meters measuring energy consumption can be located in either consumer premises or in distribution transformers. The modem draws its power from the meter terminal block and connects to the communication port of the meter. Thus this add-on electric meter reading system is non-intrusive and can be retrofitted easily to any meter. The Electric Meter Reading units use GSM/GPRS communication technology and have built-in intelligence to talk to the DLMS meter. AMR system is compatible with a 4G network to push the power consumption-billing data, load survey data, and event data to a cloud-based server, with fallback options to 3G & 2G.
The AMR solutions can push the following data from the meter at predefined periodicity hourly/daily/weekly/monthly, based on the requirements, and the same can be configured dynamically. The Data Concentrator Unit(also called Gateway) receives the metering data and sends it back to the billing system. And when you re ready to upgrade to Advanced Metering Infrastructure, our wireless automated meter reading device allows you to easily migrate your Automatic Electric Meter Reading Infrastructure to our fixed-base communication network. The AMI infrastructure allows for Real-time Demand Prediction and planning.
Typical profiles are:
The modem has a special Program Over the Air (POTA) feature to facilitate the programming of the modem remotely from the server, using security channels and procedures. The automatic electric meter reading system also provides the following remote / auto operations and functions:
Automatic meter reading (AMR) modem is employed to collect the data from various metering devices which include electricity, water and gas meters, and send the data to remote data servers, using any of the available / suitable communication technologies. The data received at the server is processed and is used for variety of functions such as billing, usage pattern analysis, tamper analysis etc.
The benefits of using an AMR modem include streamlined meter reading processes, timely billing to the customers and study of energy usage patterns. AMR implementation reduces manpower costs associated with manual meter reading, improves accuracy of meter data, faster identification of issues or anomalies, and increased operational efficiency in utility management.
Yes, SANDS AMR modems are compatible with all makes and types of DLMS meters. SANDS AMR modems have additional feature of reading the tamper counts, and initiating alarms. Contact us for more information
The data transmitted by the AMR modem is highly secure. SANDS AMR modem reads the data from the meter and send the data to the cloud or any designated data server using various encryption schemes. The received data is decrypted and is made available for any third party applications like meter data management (MDM) system or utility billing system or data analytic tool in a standard csv / json or XML formats. Thus, the data integrity and confidentiality is well protected; minimizing the risk of unauthorized access or tampering during transmission.
Yes. The AMR modem can be easily integrated with any energy management system (EnMS). The meter data will be sent to the cloud / data server by the AMR modem, and the data conversion software / service at the server will convert the meter data to the desired format and seamlessly integrate with any EnMS.
Yes. The AMR modems can be used at all the metering points a) at interface point between the captive renewable energy source like wind or solar or biogas and the utility, b) at the consumer premises between the roof-top solar and the utility bi-directional / net meters.
Yes. The AMR modems can be used at the metering point of the EV charging facility, as the source is primarily from the utility supply fitted with a tariff meter.
