Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Elektrolytische Elektrizitätszähler, bei welchen nur ein Teil des zu messenden Stromes zur elektrolytischen Wirkung benutzt wird, während der andere meistens bedeutend größere Teil einen Ohmschen Widerstand durchfließt, haben den Nachteil, daß, trotzdem Anode und Kathode aus demselben Körper bestehen, meistens eine erhebliche Konzentrations -E. M. K. auftritt, welche die Proportionalität stört. Die Konzentrations-E. M. K. kann durch Bewegung der Elektrolytflüssigkeit erniedrigt, jedoch kaum ganz beseitigt werden.Electrolytic electricity meters in which only part of the current to be measured is used for the electrolytic effect, while the other is mostly significant larger part of an ohmic resistance flows through, have the disadvantage that, anyway Anode and cathode consist of the same body, usually a considerable concentration -E. M. K. occurs, which disturbs the proportionality. The concentration E. M. K. can be lowered by moving the electrolyte fluid, but can hardly be completely eliminated will.

Die vorliegende Erfindung bezweckt nun, durch Anordnung der Schaltung die Wirkung der Konzentrations-E. M. K. zu kompensieren, so daß eine dauernd gute Proportionalität erzielt wird.The present invention now aims to achieve the effect by arranging the circuit the concentration E. M. K. to compensate, so that a permanently good proportionality is achieved.

In der Zeichnung ist die Erfindung dargestellt, und es bezeichnet A den Ohmschen Widerstand, welcher von dem größten Teile des zu messenden Stromes durchflossen wird. B ist das elektrolytische Meßgefäß, welches den verbrauchten Strom beispielsweise dadurch registriert, daß das überzuführende Metall, z. B. Quecksilber, vom Raum C in die Röhre D übergeführt wird, wobei die Höhe des Quecksilbers in der Röhre D ein Maß für die verbrauchte Elektrizitätsmenge abgibt. Parallel zu dieser Meßzelle ist nun eine zweite Zelle E angeordnet, deren Wirkungsweise z. B. dadurch kontinuierlich gemacht wird, daß das übergeführte Quecksilber vom Raum F in den Raum G transportiert wird, wobei das Quecksilber über die Kante H in den unteren Raum F zurückläuft. Sowohl in dem Stromkreis der Zelle B als auch der Zelle E sind Widerstände IK geschaltet und vor beide der Widerstand-!..The invention is shown in the drawing, and A denotes the ohmic resistance through which most of the current to be measured flows. B is the electrolytic measuring vessel, which registers the current consumed, for example by the fact that the metal to be transferred, e.g. B. mercury, is transferred from the room C into the tube D , the level of mercury in the tube D is a measure of the amount of electricity consumed. In parallel with this measuring cell, a second cell E is now arranged, whose mode of operation z. B. is made continuous in that the transferred mercury is transported from space F into space G , the mercury running back over the edge H into the lower space F. Resistors IK are connected in both the circuit of cell B and cell E and the resistor -! ..

Die Größe der Konzentrations-E. M. K. hängt nun von der Art und Konzentration des Elektrolyten, sowie von der verwendeten Stromdichte ab, desgleichen die Strommenge, welche eine Zelle abgibt, bis die Konzentrationsunterschiede ausgeglichen sind. Durch Wahl der Zellenfüllungen und der Widerstände ist es nun möglich, zu erzielen, daß die die Meßzelle durchfließende Strommenge unter allen Verhältnissen ziemlich genau proportional dem Gesamtstrome wird. Zu erwähnen ist noch, daß die Konzentrations-E. M. K. und Kapazität der Zelle E größer sein muß als diejenige der Zelle B. The size of the concentration EMF now depends on the type and concentration of the electrolyte, as well as the current density used, as does the amount of current that a cell emits until the differences in concentration are evened out. By choosing the cell fillings and the resistors, it is now possible to achieve that the amount of current flowing through the measuring cell is almost exactly proportional to the total current under all conditions. It should also be mentioned that the concentration EMF and capacitance of cell E must be greater than those of cell B.
