摘要:
When measuring the velocity of fluid flow by measuring the voltage produced by magnetic induction applied to the fluid, measurement is affected by the electrochemical potential developed at the electrodes. This may be compensated by storing the total signal produced with a first value of the induction and subtracting this stored signal from the total signal produced at a second value of the induction so that the electrochemical potential cancels out.
