Abstract:
1. A coriolis mass flow meter, especially a Coriolis mass-flow/density meter, for measuring a mass flow rate of a two, or more, phase medium flowing in a pipeline, comprising: at least one measuring tube interposed in the pipeline and through which the medium flows during operation, said at least one measuring tube having an inlet end and an outlet end; a support means, which is fixed to said inlet end and to said outlet end of said at least one measuring tube, thus holding said at least one measuring tube in an oscillation-permitting manner; an exciter arrangement, which causes said at least one measuring tube to execute mechanical oscillations, especially bending oscillations, during operation; oscillation sensors for producing a first oscillation measurement signal (x measuring and operating electronics, which deliver an exciter current (i said measuring and operating electronics produces a first intermediate value (X′ said measuring and operating electronics produces the correction value (X said measuring and operating electronics has a table memory, in which a plurality of discrete preset values for the correction value (X
