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 utility company managing rural and suburban energy networks struggled with limited data collection reach—existing tools required technicians to be in close proximity to meters, making it inefficient to monitor scattered electricity and water devices across open areas and low-density neighborhoods. This led to delayed data updates and increased operational hassle for field teams.
Tespro’s TP-RF Optical Probe addressed this with its long-range RF communication capability, enabling stable energy data capture from up to 100 meters in open spaces without on-site presence. Its dual-function design (RF + USB) also ensured seamless integration with the client’s existing backend system, no extra adapters needed.
The probe’s strong magnetic adhesion allowed quick, tool-free mounting on various meters, while its durable build and IP54 protection rating stood up to outdoor and utility room conditions. This simplified remote monitoring workflows, letting the team manage widespread energy assets more efficiently.
