Reliable Optical Communication for Smart Metering
Modern AMI systems require stable and accurate data capture at the meter level. Manual meter reading was time-consuming and error-prone.
Tespro's optical probes, including the TP-BT and USB series, enabled automatic data retrieval via optical ports, supporting various meter brands and protocols. Bluetooth and USB models offered flexibility for both field and desktop use.
Case
Product Case
A top Indian power utility company has directly procured 5,000 TP-BT-Pro Bluetooth optical probes from Tespro. Deployed across 12 states covering urban residential complexes, commercial hubs, and industrial zones, the probes streamline electricity, water, and gas meter data collection for over 2 million end-users.
The TP-BT-Pro supports BLE 5.4+SPP dual-mode communication and global protocols including IEC 62056-21, ANSI, and DL/T-645, ensuring seamless compatibility with diverse meter models used by our customers. Its 115200bps maximum data rate and 512-byte maximum frame length enable rapid batch data capture, streamlining data management for clients. The "short read/long read" dual-key design allows technicians to complete single-meter data collection in just 2 seconds—eliminating tedious manual input and significantly improving efficiency for our customers' daily operations.
Post-deployment, the client witnessed transformative outcomes: meter reading became significantly faster and more streamlined, data accuracy reached an unprecedented level, and operational costs were substantially reduced.
With the TP-BT-Pro, technicians' fieldwork was revolutionized—eliminating the need for laptops and paper forms, as data seamlessly and instantly synced wirelessly to the backend system. The client lauded the TP-BT-Pro as a pivotal tool for smart metering, emphasizing its rapid data collection capabilities and minimal maintenance requirements.
TesPro's technical team offered customized SDK support and on-site training, enabling seamless integration with the client’s energy management system. This collaboration showcases the TP-BT-Pro's scalability in utility applications and cements our position as a leading force in the smart metering industry.
