Abstract: The method comprises producing a measurement signal (s1) having a signal parameter, followed with a temporal change (?x1/?t; ?x1?/?t) of a primary measured variable (x1) and a temporal change (?y1/?t) of a disturbing variable (?1), and producing a measurement signal (s2) having a signal parameter, followed by a temporal change (?x2/?t; ?x2?/?t) of a primary measured variable (x2). The method comprises ascertaining measured values (XI) of first type representing the primary measured variable (x1) or a secondary measured variable (f(x1) ?x1?) of measured values (XII) of second type representing the primary measured variable (x2) or a secondary measured variable (f(x2) ?x2?). The method comprises using measured values (XI) of first type and measured values (XII) of second type for ascertaining an error characterizing number (Err) representing a velocity error (?XI/?XII) caused by a change of the disturbing variable (y1).

Abstract: A measuring transducer comprises a transducer housing, of which an inlet-side housing end is formed by means of an inlet-side flow divider having eight, mutually spaced flow openings and an outlet-side housing end is formed by means of an outlet-side flow divider having eight, mutually spaced flow openings as well as a tube arrangement with eight bent measuring tubes for the conveying flowing medium, which, forming flow paths connected for parallel flow, are connected to the flow dividers, wherein each of the eight measuring tubes in each case opens with an inlet-side measuring tube end into one of the flow openings of the flow divider, and in each case opens with an outlet-side measuring tube end into one of the flow openings of the flow divider. An electro-mechanical exciter mechanism of the measuring transducer serves for producing and/or maintaining mechanical oscillations of the measuring tubes.

Abstract: A method for monitoring a function of a magnetically inductive flow measuring sensor having a measuring tube and a magnetic field generator provided with at least two coils. The coils are used in the measuring mode for generating a magnetic field which penetrates the measuring tube. The method makes it possible to specifically monitor generation of the magnetic field, the coils being additionally used for function monitoring purposes. During function monitoring, at least one of the coils is used as a producer which produces a magnetic field that changes over time and penetrates at least one other coil, at least one of the other coils is used as a receiver via which a received signal induced by the magnetic field that changes over time can be derived, and functioning of the flow measuring sensor is monitored based on the received signal.
