MODULE FOR MEASURING FLOW RATE, FLOW RATE MEASURING DEVICE HAVING THE SAME, AND FLOW RATE MEASURING METHOD

摘要

A flow measurement module (110) can measure the flow of a fluid with a simple configuration. The flow measurement module (110) comprises: a fluid oscillator (111) provided in a passage (150) to generate oscillation according to the flow of a fluid flowing into the passage; a fluid oscillation frequency measurement unit (112) for measuring the frequency of fluid oscillation; a memory unit (115) for matching and storing an actual fluid oscillation frequency measured by the fluid oscillation frequency measurement unit and a corrected fluid oscillation frequency in which an error of the flow measurement module is corrected; a control unit (114) for detecting a corrected fluid oscillation frequency corresponding to the actual fluid oscillation frequency received from the fluid oscillation frequency measurement unit and outputting the detected corrected fluid oscillation frequency to a corrected fluid oscillation frequency generator (116); and the corrected fluid oscillation frequency generator (116) for generating fluid oscillation corresponding to the corrected fluid oscillation frequency.
