Galvanic electrode of an electromagnetic flow meter |
摘要 |
This galvanic electrode of a flow sensor of an electromagnetic flowmeter for measuring the volumetric flow rate of an electrically conductive liquid flowing in a measuring tube is practically absolutely fluid-tight inserted in the wall of the measuring tube and has a highly constant wetting surface. The electrode comprises a shank having a first portion which is fitted fluid-tightly in a hole in the wall, an end face and a second portion having a smaller diameter than the hole and the first portion. A wetting surface formed by the end face and a second portion of the electrode shank. This second portion forms a gap between the surface of the hole. The gap is sufficiently wide and the surface of the hole has a low surface tension so that the liquid will penetrate into and fill the gap, and the wetting surface will remain constant under all operating conditions of the flowmeter.
