It started with a conversation. In 2016, at a trade show in Mexico City, an Escort manager met a representative of TomTom Telematics (now Webfleet), one of the world’s largest fleet management providers. TomTom was open to integration on one condition: the sensors had to be wireless. That exchange planted a seed and set the direction for everything that followed.
At the time, Bluetooth Low Energy was built into virtually every smartphone, yet it was almost unknown in fleet telematics and fuel monitoring. The market had named the need, and Escort’s engineers set out to master the technology from scratch.
The first prototype
By 2018, the work had paid off. Escort produced a small pilot batch, “generation zero”, built to answer one question: does the concept work at all? It did. This was the industry’s first BLE fuel level sensor.
A year later, the first commercial TD-BLE reached the market. The wireless fuel sensor category barely existed, and Escort entered it practically alone. Its sensor was configured straight from a smartphone: no special tools, no extra wiring, no lengthy installation.
From skepticism to standard
The early years weren’t without resistance. BLE was unfamiliar territory in fleet tracking, and some partners were cautious. But the installations spoke for themselves: accurate readings, faster setup, no cables to damage or tamper with, and fewer problems on the road.
As adoption grew, so did confidence in the technology. BLE spread from a single product across Escort’s entire sensor line, and models that once required wired installation gained wireless versions. What began as an experiment became the industry default.
One million – and counting
In 2026, the millionth Escort TD-BLE went into operation, in fleets of every size and industry on every inhabited continent. The sensor born from a single conversation in Mexico City had become the benchmark for its category.
A sensor is only as useful as the system it reports to. Escort TD-BLE is integrated with the leading telematics trackers and video telematics devices: Teltonika, Ruptela, Galileosky, Queclink, Jimi IoT (Concox), BSJ, Hikvision, Navtelecom, Fort Telecom, Vega-Absolut, Meitrack, MettaX, MEGA GPS and many more. From there, data flows to Wialon, Navixy, Mapon and other monitoring platforms. A TD-BLE can join an existing fleet with no new software and no rewiring.
Wireless is now the norm
The market has made its choice. By Escort’s estimate, wireless sensors already account for 70–80% of new fuel level sensor installations in mature markets such as the CIS or India, and their share is growing fast across Latin America, the Middle East, APAC, and Africa. Leading manufacturers now offer BLE models of their own. What was a lone bet in 2018 is now the standard.
The technology didn’t follow the market. It created one.
