Abstract
An electrode for a magneto-inductive flow measuring device for determining volume flow of an electricity conductive medium flowing through a measuring tube. The measuring tube, or at least a portion of it which comes in contact with the medium, is not electrically conductive; wherein the electrode exhibits an electrode shaft and an electrode head. The electrode head contacts the medium, and the electrode shaft exhibits frustoconically shaped sealing lips arranged one after the other in the direction of the longitudinal axis of the electrode. The electrode shaft is pressed into a bore in the wall of the measuring tube. The maximum diameter of the sealing lip nearest the electrode head is greater than the diameter of the bore, and, at least in a part of the electrode shaft, the maximum diameter of any following sealing lip is greater than the maximum diameter of the preceding sealing lip.
