Abstract
A method of manufacturing an electromagnetic flowmeter and an electromagnetic flowmeter wherein the measuring electrodes do not protrude into the flow channel and instead form part of the flow channel wall. The method for manufacturing the flowmeter includes the steps of forming the flowmeter body with a central channel smaller than that which is desired for final flowmeter use, inserting into the body electrodes with tapered tips which extend into the central channel, and reaming the central channel whereby the central channel is enlarged to its final diameter and the electrode tips are cut. The cut tips form concave cross sectional areas which are continuous and flush with the central channel wall. The resultant flowmeter has measuring electrodes which do not protrude into the channel. This substantially reduces turbulent flow of the measured liquid as it passes through the measuring region of the flowmeter, and a more accurate reading results.
