Purpose

FuelScan technology is designed to ensure stable and accurate operation of Omnicomm LLS 6 AI / LLS 5 / LLS-Ex 5 fuel-level sensors when used with different types of fuel, including diesel fuel with a high biocomponent content, gasolines with alcohol-containing additives, as well as other liquids with changing dielectric properties, including oils with viscosity below 200 mm²/s (cSt).

The technology allows the measurement algorithms to automatically adapt to the current fuel characteristics, with no user involvement and without the need to recalibrate the sensor.

How It Works

A capacitive fuel-level sensor determines the liquid level from its dielectric permittivity. A change in fuel composition changes this parameter, which can cause a systematic offset in the readings of conventional capacitive sensors.

FuelScan continuously analyzes the electrical characteristics of the measuring system and automatically detects changes in the dielectric properties of the liquid.

Based on this analysis, the built-in algorithm automatically corrects the conversion coefficients applied to the measured signal, preserving measurement accuracy when the type or composition of the fuel changes. The correction is applied automatically during operation and requires no user intervention.

Key Features

FuelScan provides:

• automatic adaptation to changes in the dielectric permittivity of the fuel;
• no need to manually reconfigure the sensor when switching to a different fuel type;
• correct operation with fuels containing varying levels of biocomponents;
• compensation for changes in fuel properties caused by mixing different batches;
• stable measurements throughout the entire service life.

Supported Measured Liquids

An Omnicomm sensor with FuelScan technology is designed to work with:

• diesel fuel;
• diesel fuel containing biocomponents;
• gasolines of various grades;
• gasolines containing ethanol and other alcohol-containing components;
• motor, transformer, and bio-based oils.

Notes

• FuelScan must be enabled in the sensor settings to operate.
• Adaptation is performed automatically during sensor operation.
• When the fuel type changes, the fuel tank does not need to be recalibrated, provided its geometry has not changed.
• FuelScan is a built-in function of the Omnicomm LLS sensor and operates continuously throughout the product's service life.
