Abstract
Proposed is a thermal mass flowmeter including: a heating unit configured to heat at least a portion of a medium in a tube from the outside of the tube; a first thermometer disposed at a first position that is a downstream side from the heating unit in a flow direction of the medium; a second thermometer disposed at a second position that is a downstream side further than the first thermometer from the heating unit; and a controller configured to calculate the flow rate of the medium flowing through the tube using a phase difference due to flow of the medium between first measurement data measured by the first thermometer and second measurement data measured by the second thermometer.
