Abstract:
1. A device for indicating a position of a hydraulically actuated armature, comprising: an adjust cylinder for actuating the armature connected by at least one pressure medium line to an adjustment valve through which the pressure medium line can be switched between forward flow and backward flow; a through flow sensor arranged in the pressure medium line to convert a flow of the pressure medium in the pressure medium line into electric pulses and is connected to an electronic indicator unit for processing the pulses; wherein a program in the electronic indicator unit counts the occurring pulses and compares the numbers of pulses occurring in a flow of the pressure medium line in one direction and in an opposite direction, which determines a difference of the electric pulses of the flow of the pressure medium between the forward flow and the backward flow corresponds to the effect of compressibility of the pressure medium.
