Electromagnetic flowmeters can measure mud. The electromagnetic flowmeter utilizes the principle of Faraday’s law of electromagnetic induction. It calculates the flow rate by measuring the induced electromotive force generated when a conductive liquid flows in a magnetic field. It has the advantages of high precision, no mechanical wear, and bidirectional measurement. Mud, as a conductive liquid containing a large amount of solid particles, although it has high requirements for measuring equipment, electromagnetic flowmeters, due to their unique measurement principles and superior performance, have become the ideal choice for measuring mud flow.
