Document Type and Number:
WIPO Patent Application WO/2019/156243
Kind Code:
A1
Abstract:
A flow rate measurement device relating to one aspect of the present invention is provided with: a heating unit that heats a fluid; a temperature detection unit, which is provided across the heating unit by being aligned with the heating unit in the fluid flowing direction, and which detects the temperature of the heated fluid; a flow rate calculation unit that calculates the flow rate of the fluid on the basis of a detection signal outputted from the temperature detection unit; an angle calculation means that calculates the tilt angle of the temperature detection unit with respect to a predetermined reference surface; a storage unit that stores the relationships among the flow rate, the tilt angle, and a flow rate correction value; and a flow rate correction unit that corrects the flow rate using the flow rate correction value stored in the storage unit.
