摘要： Capacitance-type electromagnetic flowmeter capable of measuring flow rates of fluid without being affected by the flow velocity distribution. If the flowtube of the flowmeter is an open conduit, the measurement is made without being affected by variations in the liquid level. The flowmeter comprises the flowtube insulated at least on its inner surface, an exciting means for applying a magnetic field to the fluid perpendicularly to the axis of the flowtube, and a pair of detecting electrodes mounted in the flowtube. The electrodes are electrically insulated from the fluid and extend at right angles to the axis of the flowtube and also to the magnetic field. The length of each electrode taken axially of the flowtube is in proportion to the cosine of an angle made between a normal to the wall of the flowtube and an axis that is perpendicular to both axes of the flowtube and magnetic field. Where the flowmeter comprises a conduit having a free liquid surface, current signals produced from the detecting electrodes are converted by current-to-voltage converter means into voltage signals and taken out.

摘要： In electromagnetic flowmeter for converting the flow rate of a fluid to be measured to an electric signal and outputting a flow rate signal corresponding to the flow rate through detecting electrodes, exciting means intermittently causes an exciting current to flow to apply a magnetic field to the fluid to be measured, with excitation period thereof being shorter than the non-excitation period. On the other hand, a.c. coupling means obtains an a.c. signal through an a.c. coupling of the inter-electrode signals outputted from the detecting electrodes. Sample and hold means samples and holds the a.c. signal with a sampling signal having a sampling width including the portions before and after the excitation period, and outputs it as a hold signal. Switching means is changed to a reference potential before and after the period of sample and hold, and signal processing means uses this hold signal to perform a signal processing and outputs it as a flow rate signal.
