ABSTRACT
The Gas Research Institute has been sponsoring the development of a new approach for measuring the energy delivered from a pipeline or distribution system. The heart of the method is an energy flowmeter that measures directly the Btu/Hr of gas flowing down a pipeline. A field test is being established with several participants to evaluate different approaches to calibrating the energy flowmeter components. The other method uses an orifice meter and calorimeter to provide inputs to a flow computer that calculates the energy flow. The sample flow which is split off from the main stream is burned in the second component of the energy flowmeter. The corrected volumetric flow was multiplied by calorific value to obtain the energy flow. The accuracy of the energy flowmeter will be limited by the accuracy of the calibration.
