ENERGY FLOW MEASUREMENT: THE EFFECTS OF AVERAGING VERSUS CONTINUOUS MEASUREMENT

摘要

Recent advances in instrumentation have lead to an examination of the effect of different measurement techniques on the overall accuracy achievable in energy flow measurement.rnThis paper examines these various techniques used by the fuel gas industry in computing the energy flow at a measurement point. We will show that sampling interval and response of the measuring equipment (particularly chromato-graphs and calorimeters) can introduce errors into the energy flow computation. Recommendations are made on how to achieve a desired level of accuracy.
