Abstract
PURPOSE: To count the number of balls by the induction voltage produced by the difference of conductivity caused by the balls, etc. which cut across a line of magnetic induction, by providing a magnetic field to cut a magnetic flux in the flow path.
CONSTITUTION: The magnetic induction field which cuts a flow path 1 in the sectional direction is provided in a flow path 1 by an electromagnet 3, and electrodes 4 are provided to the wall of the flow path in the positions they go straight to the magnetic field, confronting with each other. When a ball 10 crosses over the magnetic induction field, the voltage induced is changed, due to the difference of conductivity. Therefore, if the ball is an insulator, the length the magnetic flux crosses over the magnetic field is extended to decrease the inducted voltage. The processor 5 to detect the induced voltage discriminates high and low relation between the voltage at the time the sea water passes through and the one at the time the ball passes through, and counts the latter only. The induced voltage becomes large, if the conductivity of the ball is larger than that of the fluid flowing through the flow path 1. The number of balls passing through can be counted by analyzing the change of voltage in the processor 5.
