Abstract
A flow rate measuring device with high precision is provided.The flow rate measuring device includes a sub-passage that takes a part of the fluid flowing in a main passage, first temperature measuring means for measuring a temperature of the fluid flowing in the passage, second temperature measuring means for measuring a temperature of a fluid flowing in the sub-passage, detecting means for detecting a flow rate of the fluid flowing in the sub-passage, and measuring means for measuring a flow rate of the fluid flowing within the main channel on the basis of an output of the first temperature measuring means, an output of the second temperature measuring means, and an output of the detecting means.
