Claim 13:
14. A meter set comprising:
a meter body for receiving a flow of mixed gas, each respective gas of the mixed gas providing a respective energy value with which to determine a total energy value for the flow of mixed gas; a meter set processing unit; and an ultrasound sensor;
wherein:
the ultrasound sensor is coupled to the meter body to generate ultrasound signals in the flow of mixed gas for transmission perpendicularly to the flow with which to determine a speed of sound in the flow;
the ultrasound sensor is configured to provide ultrasound signals or the speed of sound to the meter set processing unit; and
the meter set processing unit is configured to:
determine a concentration of the respective gases in the mixed gas in response to the speed of sound; and
present at least one of the speed of sound, the concentration of the respective gases or other data determined from the speed of sound to determine the total energy value of the mixed gas.
