A practical guide to cutting–edge techniques for flow measurement and control

Unlike any other book on the subject, this volume employs practical applications to illustrate flow measurement techniques in industrial processes. Drawing on their work at the Oak Ridge National Laboratory, five leading researchers present applications that test the limits of commercial flow instrumentation–in harsh environments, wide rangeability, and a host of challenging situations encountered in research and industry. This approach gives the reader highly effective tools for use in tackling a broad range of difficult flow measurement problems. It offers tremendous insight into what flow measurement is all about, from the underlying principles of the methodologies to state–of–the–art instrumentation–including such innovations as "smart" flow sensors. Introducing terminology, properties, units, and flow meters classification, the book:
∗ Details signal conditioning and analysis techniques that will produce meaningful results
∗ Offers tips on selecting the appropriate method for a given application
∗ Shows how modeling can improve mass flow metering accuracy
∗ Covers flow calibration and standards, as well as issues related to cost, maintenance, and ease–of–use of instruments
∗ Addresses the effect of measurement uncertainty on calibration and field measurements.

Clear, concise, and generously illustrated, Flow Measurement Methods and Applications is an invaluable resource for researchers and graduate students in physics, mechanical engineering, chemical engineering, and instrument engineering. It is a must–have reference for anyone wishing to assess flow processes accurately and reliably in the real world.
