Title:
FLOW MEASURING DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/230478
Kind Code:
A1
Abstract:
A flow measuring device, wherein the effect of the difference between a fluid temperature and an environment temperature received by a temperature sensor used in temperature compensation is reduced, and the precision of temperature compensation is improved. This flow measuring device comprises: a flow rate detector for detecting a value that corresponds to the flow rate of a fluid to be measured flowing through a main flow path; a fluid temperature detector for detecting a value that corresponds to the temperature of the fluid to be measured; and a control unit for correcting the value that corresponds to the flow rate on the basis of the value that corresponds to the temperature, and calculating the flow rate of the fluid to be measured. The fluid temperature detector and the flow rate detector are provided in different flow paths.
