The instrument allows, just as an electricity meter is used, to add up the respective consumption or, when the rotating disk is braked by a spiral spring f, to register or display the consumption with the simultaneous attachment of a recording device.



   A pointer, indicated by dotted lines, which oscillates over a correspondingly graduated scale, can be attached to the rotating disk of the counter shown in dash-dotted lines.
