11. OPERATING PRINCIPLE 11. OPERATING PRINCIPLE 11.1 Principle of Magnetic Flowmeter Operation The operating principle of the magnetic flowmeter is based on the law of electromagnetic induction which states that when a conductor moves in a magnetic field, in the direction perpendicular to the magnetic field, an electromotive force is induced perpendicular to the direction of the conductor movement and to the direction of the magnetic field.
11. OPERATING PRINCIPLE 11.2 Principal and Features of the capacitance Magnetic flowmeter The measuring principle of the capacitance magnetic flowmeter (ADMAG CA) is basically the same as that of a conventional wetted-electrode magnetic flowmeter. The capacitance magnetic flowmeter, however, picks up the e.m.f. signal generated in a liquid through the ceramic tube wall's capacitance by placing both electrodes outside the metering tube (ceramic tube) making them non-wetted.
