Reliable Optical Communication for Smart Metering
ABA systems of modern AMI demand consistent and reliable metrical data capturing. Reading of meters manually was tedious and subject to mistakes.
The optical probes of Tespro, such as TP-BT and USB series, allowed automatic access to data through optical ports, and supported many types of meters and protocols. Bluetooth and USB models were flexible both in the field and desktop.
Case
Product Case
June 10, 2025 – Poland – A leading Polish energy service provider has procured 148 TP-BT Bluetooth optical probes directly from our facility. These devices will be deployed nationwide for smart meter data collection and on-site verification across urban and rural utility networks, specifically designed to capture electricity, water, and gas meter readings.
This "operations game-changer" is reshaping traditional field workflows by replacing outdated manual logging with automated wireless data collection.Technicians no longer need to haul heavy equipment or juggle paper forms for meter reading: all data is digitally captured via Bluetooth and seamlessly synced to analysis software.
This not only eliminates transcription errors entirely but also elevates measurement accuracy to unprecedented levels, turning cumbersome on-site tasks into streamlined, hassle-free operations.
Field data shows remarkable efficiency gains: deployment is now 30% faster, meter reading errors have been cut by 35%, and maintenance expenses dropped 22%.The client specifically praised the system's plug-and-play simplicity and consistent performance in daily use, confirming they will standardize these probes for all upcoming field projects.
