Abstract
An integral trap magnetic flowmeter having an inlet in fluid communication with a sensing passage, the sensing passage intersecting a magnetic field, having electrodes for detecting a flow-dependent voltage induced by the passage of conductive liquid through the magnetic field, and having an outlet at an elevation such that the sensing passage volume normally remains filled with conductive liquid. By maintaining standing liquid in the sensing passage at a height sufficient to fill the sensing passage volume, the flowmeter's response may be made more rapid and more accurate, particularly during the early stages of a short duration liquid discharge. By providing an integral trap, installation errors may be reduced.
