Abstract: A device for measuring the quantity of a direct current flow therethrough comprises a glass tube having a body of mercury at each end which serves as an electrode. The two electrodes are separated by an electrolyte such as a mercury-salt solution. For integrating a function of the voltage and current in an electric circuit a transducer such as a Hall generator converts the function into an output current having a direct-current component which is passed through the contents of the tube. The mercurysalt solution then moves in a direction dependent on the direction of the direct current passing therethrough. The position of the mercury-salt solution represents the desired integration. The direction of the current through the tube may be reversed after each reading or it may be reversed when the mercury-salt solution arrives at predetermined positions respectively adjacent the ends of the tube.
