Abstract:
1. A calorific value measuring system, comprising: a pipe wherein a fluid flows; a flow rate controlling device controlling a flow rate of the fluid that flows with in the pipe; a temperature measuring element disposed within the pipe; a heater element, disposed within the pipe, producing heat at a plurality of heat producing temperatures; a measuring portion measuring a value for an electric signal from the temperature measuring element that is dependent on a temperature of the fluid that is flowing within the pipe, and a value for an electric signal from the heater element at each of the plurality of the heat producing temperatures; an equation storage device storing a calorific value calculating equation that uses an electric signal from the temperature measuring element and electric signals from the heater element at the plurality of the heat producing temperatures as independent variables and uses a calorific value as the dependent variable; and a calorific value calculating portion reading out the calorific value calculating equation from the equation storage device and calculating a value for the calorific value of the fluid through substituting the value of the electric signal from the temperature measuring element and the value of the electric signal from the heater element into the independent variables of the calorific value calculating equation.
