In flow-sensor arrays, elements are distributed at different positions and each sensor locally constructs the flow field components. In this paper, we report the developments of the bio-inspired artificial flow-sensors in array structures. The source localisation mechanism in fish, using the flow pattern generated from prey, is modelled. We computed the flow velocity components (parallel and perpendicular), generated by a dipole source, at the array position and based on the structure of our flow sensor. The ability of our sensors, arranged in arrays, to detect flow patterns was investigated. The model results were found to be in an excellent agreement with the measurements along virtual lateral-line and successfully demonstrate the source-distance determination
