LLS 5

LLS 5 – The World’s First Self-Adjusting Fuel Level Sensor

The Omnicomm LLS 5 fuel level sensor sets the benchmark for precision and reliability in fuel level measurement. Utilizing the patented Fuelscan technology, LLS 5 automatically adapts to the properties of the fuel being measured, ensuring an accuracy rate of over 99.5%. This sensor is ideal for both vehicles and stationary fuel storage facilities, guaranteeing seamless operation and maximum economic efficiency.

Thanks to Fuelscan Technology, LLS 5:

Analyzes the characteristics of refueled fuel

Compares the fuel with the one used for calibration

Adjusts readings to account for detected differences, ensuring benchmark accuracy

Maintains a stable accuracy of 99.5% regardless of:

- Refueling at different fuel stations

- Seasonal fuel composition changes

- The need for recalibration or reconfiguration

Next-Level Protection

LLS 5 features maximum protection against dust and moisture (IP69K) and a reinforced body for operation in the harshest conditions. Its shockproof monolithic casing, sealed connector, and stainless-steel armored cable ensure long-lasting durability. The power module with built-in 2500V galvanic isolation guarantees stable operation even in high-interference onboard networks. The operating temperature range is from -40 °C to +80 °C.
