document: Flow measurement - future directions Interest in the flow of liquids and its measurement can be traced back to early studies by the Egyptians , the Chinese and the Romans . Since these early times the science of flow measurement has undergone a massive change but during the last 25 years or so -LRB- 1977-2002 -RRB- it has matured enormously . One of the principal reasons for this is that higher accuracies and reliabilities have been demanded by industry in the measurement of fiscal transfers and today there is vigorous interest in the subject from both the flowmeter manufacturer and user viewpoints . This interest is coupled with the development of advanced computer techniques in fluid mechanics together with the application of increasingly sophisticated electronics
