About the Author

Jesse Yoder, Ph.D. (Jesse@flowresearch.com) is president of Flow Research, Inc. (www.flowresearch.com), a company he founded in 1998, which is located in Wakefield, MA. He has 28 years of experience as an analyst and writer in process control. He has authored more than 180 market research studies in industrial automation and process control and has written more than 230 published journal articles on instrumentation topics. He has published articles in Flow Control, Processing, Pipeline & Gas Journal, InTech magazine, Control, and other instrumentation publications. Study topics include Coriolis, magnetic, ultrasonic, vortex, thermal, differential pressure, positive displacement, and turbine flowmeters. He has authored two separate six-volume series of studies on gas flow and oil flow. Dr. Yoder is a regular speaker at flowmeter conferences, both in the U.S. and abroad.

Dr. Yoder studied philosophy at the University of Maryland, The Rockefeller University, and the University of Massachusetts Amherst, where he received his Ph.D. in 1984. He served as an adjunct professor of philosophy for ten years at the University of Massachusetts Lowell and Lafayette College. In 1989 he co-founded the InterChange Technical Writing Conference, which he directed for six years. He has become a world-renowned authority and expert in the area of flow measurement and market research. As an entrepreneur, author, consultant, and inventor, he has helped define the concepts used in flow measurement, and is widely respected as an innovator in this field.

Yoder lives in Wakefield, MA where he enjoys racquetball, bird-watching, and reading detective novels. Richard E. Morley (Morley@alum.mit.edu), best known as the father of the programmable logic controller (PLC), is a leading visionary in the field of advanced technological developments. An entrepreneur whose consistent success in the founding of high technology companies has been proven through more than three decades of revolutionary achievement, Morley has -- among his many accomplishments -- more than 20 U.S. and foreign patents, including the parallel interface machine, hand-held terminal, and magnetic thin film. His MIT-based background in physics has provided insight into becoming an internationally recognized pioneer in the areas of computer design, artificial intelligence, automation, and futurism. As an inventor, author, consultant and engineer, Morley has provided the R&D community with world-changing innovations. His peers have acknowledged his contributions with numerous awards, honors, and citations. Morley's medals of achievements are from such diverse groups as Inc. magazine, the Franklin Institute, the Society of Manufacturing Engineers, and the Engineering Society of Detroit. He has also been inducted into the Manufacturing Hall of Fame.
