摘要

A calorific value calculation formula creation system (20) includes: a second measurement module (301) which obtains a measured value of a second resistance of the temperature measurement element coming into contact with a mixed gas, and a measured value of the first resistance of the heater element coming into contact with the mixed gas; a measurement correction module (323) which corrects the measured value of the first resistance of the heater element coming into contact with the mixed gas, based on the correction coefficient; and a calorific value calculation formula creation module (302) which creates a calorific value calculation formula, based on: calorific values of the plurality of gases included in the mixed gas; the measured value of the second resistance of the temperature measurement element coming into contact with the mixed gas; and the corrected measured value of the first resistance of the heater element. The calorific value calculation formula is represented by: the second resistance of the temperature measurement element that is set as an independent variable in the calorific value calculation formula; the first resistance of the heater element that is set as an independent variable in the calorific value calculation formula; and a calorific value of the mixed gas that is set as a dependent variable.
