System for automatic calculation of corrected differential pressure measurement in refuelling applications. From differential pressure input values and corresponding flow rate signals, the DPGUARD® determines the optimum differential pressure curve of the filtration equipment and outputs the corrected differential pressure values of the filtration system depending on the current operating parameters.
DPGUARD® is available in two variants: DPGUARD® gold, with display and housing and DPGUARD® silver, without display and housing.
