Abstract

A method and a device for measuring the angular distribution of a liquid jet ejected from a spray element (5), particularly of a fuel jet ejected from a fuel injector, is proposed. Partial spray quantities are detected by catch containers at a plurality of measuring coordinates arranged in a spatially or planarly distributed manner. The catch containers each contain a plurality of measuring coordinates, and the measurement is carried out in a multiply repeated manner using catch containers, which are rotated about an axis of rotation with different angles of rotation.
