The CROMAID device was specifically designed to monitor in real time the behavior of fuel pattern. SmartProbe is an accessory located near at the bottom of the tank.
CromaID is an electronic device that directs light beams (in visible and non visible spectrum) through the fuel, performing an statistical analysis of the result of light absorption. For each type of fuel (like ethanol, gasoline or diesel) each light beam is absorbed differently, because each product has a distinct absorption identity.
Directs light beams (in visible and non visible spectrum) through the fuel, performing an statistical analysis of the result of light absorption. For each type of fuel (like ethanol, gasoline or diesel) each light beam is absorbed differently, because each product has a distinct absorption identity. This colorimetric assessment type, but without relationship with a chemical analysis, allows small changes to be observed in standard product.
To do an accurate analysis, the CromaID evaluate automatically the first’s deliveries in “learning” mode. With this “learning” it can define the correct parameters of how to evaluate the product inside the tank. The parameters has direct relation to the product variation and are considered to determine the exact behavior of each product.
When using markers the efficiency of the detection could be better due a standardization and low variance in regular refueling, but even without markers, normally each company has its own standard, that contribute to better discrimination.
Tolerances are classified with their intensities and are shown in the dashboard screens.
Dashboards inform the intensity of pattern change. Patterns that exceed the normal range is defined as a "LIGHT", "MODERATE" or "SEVERE".
In the figure below, we can see the behavior of each CromaID beams. The vertical lines indicates a delivery occurrence. Specifically in this tank were four deliveries. This behavior occurred in a gasoline tank that before delivery we have a mixture of 20% Ethanol. After that delivery there were legal change of mixing Ethanol, moving to a new rate of 25%.
Observe the reaction of each light beam with the increase of 5% Ethanol in Gasoline. Each light beam began to operate on another level with different impacts, identifying a significant change in product. The CromaID analyzes the variation of the five beams to inform this change and the change intensity in the dashboard.
