The TD-BLE series Bluetooth fuel level sensor is a wireless fuel level monitoring solution designed for vehicle fuel tanks, construction machinery, fixed storage tanks, and industrial equipment. Utilizing capacitive liquid level measurement, it enables continuous fuel level detection for light petroleum products—including gasoline and diesel—and wirelessly transmits real-time fuel level data via Bluetooth Low Energy (BLE) to Bluetooth gateways, in-vehicle terminals, or fleet management platforms.
Compared with traditional wired fuel level sensors, the TD-BLE eliminates complex signal cabling, offering greater installation flexibility. Its self-powered design features a replaceable industrial-grade lithium battery, reducing vehicle rewiring and post-installation maintenance efforts—ideal for new installations, retrofits, and fuel tank monitoring applications where wiring is impractical. With stable, low-power BLE communication, the device uploads fuel level data at user-configurable intervals, enabling timely awareness of tank level changes and fuel consumption patterns.
High-Precision Fuel Level Monitoring
The sensor adopts capacitive measurement to detect changes in dielectric properties inside the tank and derive accurate fuel level information—optimized for light petroleum products such as gasoline and diesel. It supports fuel tank lengths of 150–2500 mm for vehicles and can be customized for fixed storage tanks with measurement ranges up to 6000 mm, delivering flexible liquid level management across diverse container types.
Low-Power Bluetooth Wireless Transmission
The TD-BLE supports Bluetooth LE (BLE) wireless communication operating in the 2.402–2.480 GHz ISM band, with a typical line-of-sight communication range exceeding 10 meters. It transmits real-time fuel level data to nearby Bluetooth-enabled terminals or gateways, which then relay the data to fleet management platforms—enabling remote viewing, historical logging, and centralized fuel data management. This low-power communication architecture ensures both transmission reliability and extended battery life.
Self-Powered Design for Simplified Installation & Maintenance
The device features an independent power architecture with a maximum supply voltage of ≤3.6 V and integrates a replaceable industrial-grade lithium battery. This design minimizes dependency on existing vehicle wiring, making it ideal for projects prioritizing installation efficiency, safety, and reduced long-term maintenance costs. All cable harnesses use sealed, waterproof connectors; routine operation requires no disassembly.
Robust Performance in Harsh Industrial Environments
The TD-BLE achieves an IP69K ingress protection rating, ensuring reliable operation in demanding environments—including dust, moisture, vibration, and high-pressure washdown conditions commonly found in vehicles, construction machinery, marine applications, and industrial facilities. It operates continuously within a temperature range of −45°C to +50°C, with extended functionality down to −60°C and up to +85°C. Certified for intrinsic safety per Ex ia IIB T6 X, it meets stringent safety requirements for fuel level monitoring in hazardous locations.
Typical Application Scenarios
The TD-BLE is widely deployed for fuel monitoring in tanker trucks and logistics fleets to track fuel consumption; for fuel tank management in heavy equipment such as excavators and loaders; and for liquid level monitoring in fixed storage tanks, marine systems, and industrial equipment. When integrated with Bluetooth gateways, in-vehicle telematics terminals, or IoT platforms, users gain capabilities including automated fuel level data collection, fuel consumption analytics, alerts for abnormal level fluctuations, and remote tank management.
