Measuring flow of flowing medium according to magnetic induction principle

摘要: The flow measurement involves a magnetic field created by coils (2,3) connected to current source (7), the having at least one component vertical direction of flowing medium. pipe (1) has electrodes (4,5) on either side medium and field. A voltage is delivered as for through via electronic unit (6) an amplifier (8) processor circuit (9). periodically reversed in polarity, which carried out intervals, time delaying next reversal polarity. phase jump 180 deg. less than 360 executed. voltages are used reference interval constant DC field, extended postponed pole reversal.
