"Electric Flux" through an area is defined as the electric field multiplied by the area of the surface projected in a plane perpendicular to the field. Electric Flux is a scalar-valued quantity.
$\Psi = \int_S D \cdot e_n dA$, over a surface $S$, where $D$ is electric flux density and $e_n dA$ is the vector surface element.
