A method and an arrangement in connection with anesthesia equipment comprising a gas mixer (1), a connecting stud (4) having a flow connection with the gas mixer (1), and a vaporizer (2) to be arranged in the connecting stud (4) for vaporizing an anesthetic, whereby the vaporizer (2) is equipped with a mechanical regulator (6) in order to regulate the set value of the vaporization. In order to achieve a flexible solution, a device (7) equipped with a flow measuring unit is arranged to measure the flow of the vaporizer (2). A reference scale (8) corresponding to the reference scale of the vaporizer is arranged in a moving regulating member of a mechanical regulator (6). The arrangement is equipped with a reader device (9) arranged to read the position of the reference scale (8), and means for calculating the consumption of anesthetic on the basis of the flow data obtained from the device (7) equipped with the flow measuring unit and the set value of the vaporization obtained from the reader device (9).
