Abstract: A counting apparatus comprising a drum counting mechanism and a step motor for driving the drum counting mechanism. A housing for the drum counting mechanism includes a wall which forms a part of the housing for the step motor, the step motor including a rotor with a rotor shaft, which shaft extends through the wall. The step motor includes a stator coil which is supported on an extending portion of the housing for the step motor. Alternatively, a bearing and flange unit may be provided which extends through an opening in the common wall and which may have an extending portion on which the stator coil is mounted in surrounding relationship.

Abstract: A flow-through meter for liquid or gaseous media including a housing through which the medium flows. A floating body is disposed within the housing for movement under the influence of a lifting force produced by an increased flow of the medium through the housing. The floating body is rigidly connected to a weight body of ferromagnetic material by a connecting rod which serves to locate the weight body in the field of an induction coil mounted within the housing. A restoring biasing member is located between the weight body and an internal collar abutment of the housing, and exerts a force on the weight body counteracting the lifting force. The meter further includes a damping piston located between the housing collar abutment and the restoring spring, and disposed for axial movement lengthwise of the connecting rod.
