Abstract: The invention relates to a field device of measurement- and automation technology, comprising: a measuring transducer which is adapted to register at least one measured variable and, at any one time, to output at least a first measured value representing the measured variable; a display unit which is adapted to display measuring- and/or operating parameters; and an electronic measuring/operating circuit which is adapted to operate the measuring transducer and/or the display unit, as well as to calculate from the first measured value a derived, second measured value. The display unit has a screen that has a first region with a first display technology and a second region with a second display technology. The first region is embodied reflectively or transreflectively and the second region is embodied transmissively.

Abstract: The invention relates to a method for operating a magneto inductive flow measuring device and to a magneto inductive flow measuring device, wherein at least one magnet system having at least one coil produces a periodically polarity changing magnetic field extending essentially perpendicularly to a longitudinal axis of the measuring tube for inducing a flow dependent voltage in the medium, wherein in a measuring phase for registering at least one voltage value for ascertaining flow velocity or volume flow an essentially constant magnetic field is produced, which is reverse poled in a polarity reversal phase, wherein energy supply during the polarity reversal phase occurs completely from a capacitor.

Abstract: The connection apparatus of the invention comprises a platform (200), a plug connector (15) having a plug connector part (19) secured to the platform (200) and electrically connected to the circuit of the field device and a plug connector part (20) connectable with the connection cable and complementary to the first plug connector part (19), as well as a lid (16) held movably relative to the platform (200) for at least partially covering the plug connector (15) formed by connecting the plug connector parts (19, 20).
