Abstract

PURPOSE: To facilitate the measurement of flow rate of a magnetic liquid, by magnetizing a portion of the magnetic liquid in a duct and measuring the time difference between the starting of the magnetization and the passing of the magnetized portion through a downstream detector.
CONSTITUTION: An exciter 2 and the detector 3 are provided at a prescribed distance L from each other on the duct 1 through which the magnetic liquid flows. The portion of the liquid is magnetized by the exciter 2. The time of passing of the magnetized portion through the detector 3 is detected in terms of electromagnetic induction. The time difference between the starting of the magnetization and the passing through the detector 3 is measured. The flow rate of the magnetic liquid is computed by a flow rate calculator 13, changed into an analogue quantity by a D-A converter 14 and recorded in a recorder 15.
