Der Gegenstand der Erfindung ist in der beiliegenden Zeichnung schematisch in einem Ausführungsbeispiel dargestellt.

Das Instrument gestattet, genau wie ein Stromzähler benutzt, den jeweiligen Verbrauch zu summieren oder auch bei Abbremsung der rotierenden Scheibe durch eine Spiralfeder f den Verbrauch bei gleichzeitiger Anbringung einer Registriervorrichtung zu registrieren oder anzuzeigen.
An der strichpunktiert augegebenen rotierenden Scheibe des Zählers kann ein punktiert angedeuteter Zeiger augebracht sein, welcher über einer entsprechend graduierten Skala schwingt.

The object of the invention is shown schematically in an exemplary embodiment in the accompanying drawing.

fluctuations have no influence on the measurement result. 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.
