description A method for the measurement of a physical parameter of a liquid by means of a sensor having at least one measuring tube for conducting the liquid, wherein the measuring tube can be excited to vibrate in at least one flexural vibration mode, comprises: determining at least one current value of a vibration parameter of the flexural vibration mode; determining a measurement value of the physical parameter according to the current value of the vibration parameter, wherein the measurement value is compensated in respect of the resonator effect according to a current value for the natural frequency of the flexural vibration mode and according to the sound velocity of the liquid conducted in the measuring tube, wherein the value for the sound velocity is provided independently of the vibrations of the measuring tube.
