FIELD: physics.
SUBSTANCE: vibration-type flow meter (5) has a flow meter unit (10), having one or more feed tubes (103), a meter temperature sensor (204) configured to measure temperature Tm of the meter, an ambient medium temperature sensor (208) for measuring temperature Ta of the ambient medium and a measuring electronic apparatus (20) connected with the meter temperature sensor (204) and the ambient temperature sensor (208). The measuring electronic apparatus (20) is configured to receive temperature Tm of the meter and temperature Ta of the ambient medium and determine the derivative of temperature Tf-deriv of the flowing liquid material in the vibration-type flow meter (5) using temperature Tm of the meter and temperature Ta of the ambient medium.
EFFECT: high accuracy of determining temperature of flowing liquid material.
