Electromagnetic flow meter










Image Number 4 for United States Patent #4409846.

An electromagnetic flow meter with less power consumption in which an instantaneous pulsate current with alternately changing polarity at given intervals is fed into an exciting coil, and a velocity of flow of fluid is calculated by using a voltage produced between electrodes in accordance with a residual magnetic flux of a magnetic circuit and a flow velocity of the fluid when no exciting current flows.
