description PROBLEM TO BE SOLVED: To provide a method and system for surely detecting existence of different-phase slag in a multi-phase flow. SOLUTION: A detection method and system executes processes of: outputting an output signal corresponding to a mass flow rate of the multi-phase flow from, for example, a strain gage 24 by using a mass flowmeter including an orifice plate 8; finding a rate of change of a signal waveform of the output signal by a signal processing device 32; and comparing the signal waveform of the output signal with a regular signal waveform determined beforehand as the regular signal waveform of the output signal assumed to be detected when slag does not exist in the multi-phase flow, and determining issue of alarm or information showing that the slag exists in the multi-phase flow, when the signal waveform of the output signal has a high rate of change exceeding a prescribed tolerance with respect to the rate of change in the regular signal waveform.
