A meter electronics ( 20 ) for a flow meter ( 5 ) is provided according to an embodiment of the invention. The meter electronics ( 20 ) includes an interface ( 201 ) for receiving a vibrational response and a processing system ( 203 ). The processing system ( 203 ) receives the vibrational response, vibrates at least one flowtube ( 130 ) of the vibratory flow meter ( 5 ) and generates a first tube period tau?m 1#191 for a first flow material m 1 , vibrates the at least one flowtube ( 130 ) and generates a second tube period tau?m 2#191 for a second flow material m 2 , and determines one or more of a stiffness coefficient C 1 or a mass coefficient C 2 from the first tube period tau?m 1#191 , a first density rho?m 1#191 , the second tube period tau?m 2#191 , and a second density rho?m 2#191.
