FIELD: physics. ^ SUBSTANCE: within operation measuring tube of Coriolis acceleration flowmeter/ densimeter is driven by bending vibrational motion using exciter. Electronic unit of flowmeter develops intermediate value (X'm) of mass flow deduced from measuring signals (xs1, xs2), representing input and output vibrations of measuring tube, second intermediate value (X2) deduced from one measured operating parameter of Coriolis acceleration flowmeter: one measuring signal (xs1, xs2) of vibration, excitation current (iexc) and current parameter and representing measure of medium phase portion. Using intermediate value (X2), adjustment value (Xa) of intermediate value (X'm) is calculated. Value (Xa) by intermediate value (X2) is chosen from number of preset values saved in tabular memory. Using values (X'm) and (Xa), measured value representing mass flow (Xm) is calculated. ^ EFFECT: higher measurement accuracy of non-uniform environments and simplified implementation. ^ 13 cl, 5 dwg |
