Abstract An imaging electromagnetic flowmeter is used to amplify the signal of signal input instrument amplifier by computer controlling electronic shifting switch with multipoint selection after the created induction potential via input impetance amplifier converting circuit when electrofluid flows through the multiple transducer and then the signal is sent to the next filtering circuit for high and low pass filtering by synchronous sampling circuit. The signal is sent to signal amplifier circuit for amplifying and A/D converting circuit. The A/D converted data is sent into the data processing system of the computer and to be displayed on LCD screen.
