Basic Circuit of the Transmitter
The converter can supply the uncontrollable current to the coil in the sensor of
electromagnetic flow meter. The head amplifier amplifies the electromotive force from
the sensor and converts it into standard signals of current or frequency so that the
signals can be used for displaying, controlling, and processing.
