In which type of electromagnetic flowmeter, the probe magnet is energized with sine wave?(a) Sine wave electromagnetic flowmeter(b) Square wave electromagnetic flowmeter(c) Sawtooth wave electromagnetic flowmeter(d) Impulse wave electromagnetic flowmeterThis question was posed to me during an internship interview.This interesting question is from Cyber Medicine topic in section Telemedicine Technology of Biomedical Instrumentation

Answer»

The correct CHOICE is (a) Sine wave electromagnetic flowmeter

The best explanation: In a sine wave flowmeter, the PROBE magnet is energized with a sine wave and consequently the induced voltage will also be sinusoidal in nature. The major problem encountered with the sinusoidal type of magnetic field is that the blood vessel and the fluid CONTAINED in it act as the secondary coil of a TRANSFORMER when the probe magnet is EXCITED.
