The working principle of the electromagnetic flowmeter is based on the Faraday law of electromagnetic induction. When a conductor moves in a magnetic field,an induced electric potential is generated at both ends of the conductor perpendicular to the direction of the magnetic field.The magnitude of the electric potential is proportional to the motion velocity of the conductor and the magnetic induction strength of the magnetic field.
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. |
