<P>PROBLEM TO BE SOLVED: To provide a flow rate calibration method, a flow rate calibration device, and a reduced heat quantity calculating device capable of measuring precisely a flow rate for calculating a reduced heat quantity while restraining a cost increase. <P>SOLUTION: The reduced heat quantity calculating device 5 includes a correlation data storage part 54e storing correlation data between an output obtained from a flow sensor 53 and a flow rate value therein, and a flow rate calculating part 54f for calculating the flow rate value based on the correlation data stored by a correlation data storage part 54e means when the output is obtained from the flow sensor 53. The flow rate calibration method stores outputs obtained by making fluids having three known flow rate values of the rated minimum flow rate value F1, the rated maximum flow rate value F2 and a change point flow rate value F3 flow through in the flow sensor 53, and calibrates the correlation data so that the stored outputs are conformed to the three known flow rate values on the correlation data stored by the correlation data storage part 54e. <P>COPYRIGHT: (C)2013,JPO&INPIT |
