Application Examples
Flow direction can be changed after installation.
Measure the volume flow of inductive liquid by applying the Faraday’s law
of induction “when conductive object is moved through a magnetic field,
electromotive force will be generated.”
Electromotive force (E) is proportional to fluid velocity (V) multiplied by magnetic flux density (B).
Volume flow is calculated by converting measured electromotive force (E).
Oval fluid passage is used to improve the magnetic flux density by small amount of current.
