Title:
ERROR DETECTOR CIRCUIT FOR MAGNETIC FLOW MEASURING APPARATUS
Document Type and Number:
Japanese Patent JP3199460
Kind Code:
B2
Abstract:
PURPOSE: To output a signal when an input to a measuring circuit is insulated in a magnetic fluid measuring apparatus for measuring the flow rate of fluid passing through a pipe.
CONSTITUTION: The fluid passing through a pipe flows in contact with electrodes 4, 5, which output signals +Us, -Us to alarm circuits 12, 13. As a result, if the difference of the amplitudes or noise components of the absolute values of both the signals +Ux, -Us are detected, an alarm signal is output by an output unit.
