When the conductive fluid flows at an average velocity of V(m/s) through an insulating catheter with an inner diameter of D(m) containing a pair of measuring electrodes,the pipeline is in a magnetic field with a uniform magnetic induction strength of B (T),then the induced electric potential E(V) is generated on a pair of electrodes.Its direction is perpendicular to the magnetic field.
Faraday's law of electromagnetic induction is: E=B*D*V £¨1£©
Volume flow is: (2)
Formulas (1) and (2) indicate that: (3)
Therefore, electromotive force can be expressed as: (4)
When B is a constant, a certain fixed caliber D is also a known number, in formula(3) (a constant), then formula (3) can be overwritten to
By formula (5) it is seen that the flow QV is proportional to the electric potential E. |
