IPC: G01F1/20
Filed: 1988-06-10
Abstract: PURPOSE:To prevent corrosion caused by the action of a battery by providing an external ball with a partition to separate a pair of hemi-spherical internal cores made of a ferromagnetic material. CONSTITUTION:A ball 3 is made up of a pair of hemi-spherical internal cores 12 made of a ferromagnetic material and an external ball 10 having a partition 11 for guiding the internal cores 12 separating it and the external ball 10 is made of a non-magnetic material and has a waterproofing. In use as flow rate sensor, a flow passing through a fixed wing 2 of a passage causes a spiral flow proportional to a flow rate and hence, revolutions of the ball 3 become proportional to the flow rate. Each time the ball 3 approaches or separates from a magnetoresistance element 6, a magnetic flux of a permanent magnet 7 changes and in response to this change, a resistance of the magnetoresistance element 6 also changes synchronizing resolutions of the ball 3. The resistance change is extracted to measure a flow rate. In this manner, as pair of internal cores comprising a ferromagnetic material is separated with the partition of the external ball, a gap corrosion due to the action of a battery is reduced significantly.
