ABSTRACT:
An electromagnetic flow meter interposable between ends of upstream and downstream pipes. The flow meter comprises a measuring pipe of nonmagnetic material for fluid flow therethrough; two magnetic flux generating units facing toward and forming gaps with the outer surface of the measuring pipe; and two casing units of magnetic material enclosing the magnetic flux generating units and the measuring pipe, with the magnetic flux generating units being adjustably secured to the casing units. One of the casing units or the measuring pipe has projections which make the axes of the casing units and the measuring pipe coincide.
