A process meter for measuring at least one physical process variable of a medium stored in a container or flowing in a line, comprising: a transducer including a sensor arrangement providing measurement signals (s<SUB>1</SUB>, s<SUB>2</SUB>), the sensor arrangement having: at least a first sensor providing at least a first measurement signal (s<SUB>1</SUB>) in response to the physical process variable being measured, particularly to changes in the process variable, and at least a first temperature sensor mounted in the transducer for locally sensing a first temperature, T<SUB>1</SUB>, in the transducer, and by means of the at least one temperature sensor, at least a first temperature measurement signal (theta<SUB>1</SUB>) representing the first temperature, T<SUB>1</SUB>, in the transducer; and meter electronics which, using at least the first measurement signal (s<SUB>1</SUB>) and a first correction value (K<SUB>1</SUB>) for the at least first measurement signal (s<SUB>1</SUB>), derive at least one measured value (X) currently representing the physical variable, wherein: during operation, the meter electronics determine the first correction value (K<SUB>1</SUB>) from a temporal variation of the at least first temperature measurement signal (theta<SUB>1</SUB>) by also taking into account temperature values sensed in the past by means of said first temperature sensor.
