Document Type and Number:
Japanese Patent JPS5812533
Kind Code:
B2
Abstract:
An electromagnetic flowmeter having a flow tube interposed in a normally less-than-full fluid line. A pair of arcuate electrodes are mounted in the flow tube at opposed positions spanning a substantial portion of the total circumference of the inner wall of the tube, whereby the electrodes are operative with respect to fluid in the tube in a range extending from a level close to empty to completely full. The electrodes which are in direct contact with the fluid have an inverted T formation, whose vertical leg conforms to the inner circumference of the tube, and whose horizontal base extends along the bottom of the tube, thereby maintaining a large portion of the electrode area in contact with the fluid at all times. Associated with the flow tube is an electromagnet that is excited by a periodically interrupted direct current to establish a magnetic field in the tube which is intercepted by the fluid passing therethrough to induce a signal in the electrodes.
