Overview

TD-BLE is a wireless capacitive fuel level sensor that communicates over Bluetooth Low Energy, eliminating wiring between the sensor and the tracking device. Its vandal-proof housing withstands impact, temperature swings and humidity, and pairs with any GPS tracker that supports a BLE terminal — including onboard "black box" data storage for offline logging.
