The Omnicomm LLS 4 Digital Fuel Level Sensor is a high-precision capacitive fuel sensor designed for professional fleet fuel monitoring and telematics systems. Using a digital RS-485 interface, the LLS 4 delivers stable, noise-free fuel level data with up to 99% accuracy. It is ideal for trucks, buses, generators, construction equipment, and industrial fuel tanks where fuel control, theft prevention, and consumption analysis are critical.
The Omnicomm LLS 4 Digital Fuel Level Sensor is part of Omnicomm’s globally trusted LLS (Level Liquid Sensor) series. It uses capacitive measurement technology, where changes in fuel level are converted into precise digital signals.
Unlike analog sensors, the LLS 4 communicates via RS-485 digital protocol, ensuring high resistance to electrical interference and reliable performance over long cable distances. The sensor supports multi-point calibration, allowing accurate fuel measurement even in irregular or large fuel tanks.
With a rugged metal body and IP68 protection, the LLS 4 is built for harsh operating environments. When integrated with GPS trackers and fleet management software, it enables fuel consumption monitoring, refueling detection, idle fuel analysis, and fuel theft alerts, helping businesses reduce operational costs and fuel losses.
