Abstract

The present invention relates to a measurement method (100) for determining at least two physical properties of a fluid (1) of a pipe-fluid system (150) comprising a first property (1a) and at least a second property (1b) of the fluid (1) by using a measurement system (200), wherein the measurement system (200) comprising a vibration sensing device (210) that is configured to measure a vibration of the pipe-fluid system (150), and a processing device (220), wherein the method (100) comprising the steps of: - measuring (102), by the vibration sensing device (210), a frequency spectrum (10); - extracting (104), by the processing device (220), from the measured frequency spectrum (10) a first vibration frequency mode (12a) and at least a second vibration frequency mode (12b); - obtaining (106), by the processing device (220), a dependency (14) of at least two physical properties of the fluid (1) on at least two vibration frequency modes (12a, 12b) that comprises of at least one of the following: a sensitivity factor per vibration frequency modes per physical property (1a, 1b) and a first initial vibration frequency mode value (12c) and at least a second initial frequency mode value (12d); - calculating (108), by the processing device (220), based on the extracted first and at least second vibration frequency modes (12a, 12b) and the obtained dependency (14) the first property (1a) and at least the second property (1b) of the fluid (1) of the pipe-fluid system (150).
