A capacitive fluid sensor is provided that utilizes a flexible substrate. It has a plurality of conductive members supported on it which are connected to a connecting end. The conductive members are arranged in an array and are aligned with a longitudinal axis of the substrate and the members are separated by intervening spaces. The intervening spaces are arranged so that they cross the longitudinal axis at an angle such that adjacent conductive members overlap each other when viewed from a side edge of the sensor. Such an arrangement provide more accurate measurement of fluid levels within containers.
