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 major African energy utility faced challenges with fragmented data collection—its field teams used a mix of tablets, PDAs, and laptops, while legacy meters lacked unified connectivity. Seeking a versatile solution to streamline electricity and thermal meter data capture, the company turned to Tespro’s TP-PDA series optical probes.
The TP-PDA excels in versatility, featuring RS232/USB/Type-C interfaces and terminal adaptability that ensures seamless integration with the client's existing hardware infrastructure. Its innovative magnetic attachment mechanism allows for tool-free, rapid installation on meters, eliminating the need for complex setups. Coupled with a 2-meter standard cable for enhanced on-site maneuverability, the device offers true plug-and-play functionality. With data transmission speeds reaching up to 115200bps, technicians can conduct accurate readings swiftly, streamlining the entire process without technical hurdles.
The utility deployed 500 TP-PDA probes across urban and rural areas. Before implementation, device compatibility issues plagued their operations, and the need for hardware overhauls added significant costs. With TP-PDA, these compatibility issues were completely resolved as it seamlessly worked with all existing terminals, eliminating the requirement for costly hardware upgrades. Additionally, the straightforward and reliable nature of TP-PDA solidified its role as a key component in the smart metering upgrade, effectively addressing operational hurdles and cost concerns.
This case highlights the TP-PDA series’ role as a flexible, cost-effective solution for utilities with diverse hardware setups, reinforcing Tespro’s legacy of delivering adaptable energy data collection tools.
