Abstract
An electromagnetic flowmeter for measuring a flow rate of a fluid which flows through a measuring pipeline arranged in a controlled magnetic field. The electromagnetic flowmeter includes an electromagnet unit excited by an exciting current, for generating a magnetic flux in the controlled magnetic field, a magnetic sensor unit for measuring a density of the magnetic flux generated in the controlled magnetic field, and a signal generating unit for generating an electric signal according to the density of the magnetic flux generated in the controlled magnetic field and a flow speed of the fluid, an adjusting unit, coupled to the magnetic sensor unit, for adjusting the magnetic flux density to a predetermined value by controlling the exciting current. The flowmeter also includes a measuring unit for measuring the electric signal at a predetermined time cycle determined by a frequency of the exciting current, thus causing the electric signal to be measured every time the magnetic flux density is at the predetermined value. A computation unit computes the flow rate of the fluid based on the measured electric signal and an exciting current at a time when the measured electric signal is detected.
