Abstract: An apparatus for determining at least one size parameter of an object whether it is moving or at rest comprises an optoelectronic measuring system, which comprises an evaluating unit and transmitting and receiving means, which are disposed in a measuring plane that extends substantially at right angles to the longitudinal axis of the object. The measuring plane extends in a measuring portal, which comprises at least two measuring beams, which include a predetermined angle with each other. Each of said measuring beams has a side face which faces said measuring plane and on said side face is provided with at least one row of receiving elements. Associated with each of said rows of receiving elements is a transmitting element, which is disposed in the measuring plane at a fixed distance from the associated measuring beam and is adapted to be periodically activated to emit a fanlike light beam, which is incident on the receiving elements of the associated row thereof.
