ABSTRACT:
A device for use with a gas flow meter for automatically averaging the temperature of a gas flow with respect to its volume, includes a temperature sensing device for sensing the temperature of the gas flow through the flow meter and means responsive to the output of the temperature sensing device for deriving an output signal representing the temperature recorded by the device at any instant. Successive flow signals from the flow meter each representing the flow of a predetermined volume of gas are totalled in a first summing means, and the output signal derived from the temperature sensing device is entered into a second summing means whenever a flow signal is entered into the first summing means such that the second summing means totals successive temperature signals. The total stored in the second summing means is automatically divided by the total stored in the first summing means whenever the totals are updated, and the output from the dividing means thereby represents the average temperature of the total volume of gas which has flowed.
