This book is the first to present flow measurement as an independent branch of the measurement techniques, according to a new global and unitary approach for the measurement of fluid flow field, starting from finding its unitary fundamental bases. Furthermore, it elaborates the method of unitary analysis/synthesis and classification of compound gauging structures (CGS): the UASC – CGS method. These methods ensure, in a systematic and predictable way, both the analysis of the types of flow meters made until present (i.e. CGS) and the synthesis of new types of flowmeters. The book outlines new contributions in this field, including separately, for flow meters, and CGS: structural schemes and their unitary, unitary classification, unitary logical matrix, method of unitary analysis/synthesis and classification.

Horia Mihai Moţit, PhD, graduated from Automatic Control and Computers Faculty, University Politehnica, in Bucharest, Romania, and received a PhD in flow measurement in 2000. He developed a prodigious career with over 30 years of research, design, and production of a considerable variety of types of flow meters (variable area flow meters, insertion flow meters, oscillating piston meters, bypass flow meters, flow measurement structures using flumes, test stands for volumetric calibration, respectively, for gravimetric calibration of flow meters). He received the distinguished awards for creativity: National Prize for Patented Inventions (2nd place) in 1985, National Prize for Patented Inventions (1st place) in 1987. He has achieved a significant number of patents in the field, regarding new types of industrial flow meters (then produced in a large number) including the world premiere "method for the determination of conversion curves of flow scales of gas variable area flow meters, using only water."
Dr. Moţit is the author of several reference books in the field, of which the most relevant include the following: Industrial Flow Measurement (1988), Meters (water meters, heat meters, gas meters) (1997), and Variable Area Flow meters (2006). He developed an intense scientific activity in the flow measurement field, by presenting more than 30 lectures to national and international symposia/congresses and publishing more than 35 articles in national technical and scientific journals. Dr. Moţit was Director of the R&D department for flow measurement of Measurement and Control Instrument Company S.A. in Otopeni (Bucharest), Fine Mechanics Company S.A. in Bucharest, Mechatronics and Measuring Technique Institute in Bucharest. Dr. Moțit was then the Technical Director of Schlumberger Industries in Romania.
Dr. Moţit is the Founding President of the Romanian Technical Standardization Committee for Flow Measurement (1990–2006), the member and Romania’s representative at IMEKO/TC9—Flow Measurement Committee (1991–present), the Founding President of A.A.I.R.—Control and Instrumentation Association of Romania (1990–present), and the Editorial Director of Automation and Instrumentation journal (1991–present).
"Comparing with the classification of flow meters according to BS EN7405 (British Standard) Method of Unitary Analysis, Synthesis and Classification of Flow Meters (Method of UASCF) is a great advance. This book is a good reference for the flow measurement community and a good textbook for students in the field."

"Establishing a unitary analysis/synthesis and a classification of a metrological system is a complex and uncommon exercise which here ultimately relates generally to all, not only to one particular technology. Here, the work done using "UASCF" (then UASCF-CGS) methods to establish a unitary universal analysis/synthesis and classification of flowmeters is impressive, complete, and very convincing, thanks to a very high degree of rigor of Dr. Motit and his thorough knowledge of this field of flow measurement. Finally, in addition to identifying the different basic functions and parameters that are taken into account in different known flow metering technologies, the reader will have in hand an interesting logical tool to predictable imagine new concepts and evaluate their impact on the determination of new desired flow measuring devices."

"This is an interesting book, which is useful for a large community. The scientific level and content of the book is high and very clearly presented."
—Ioan Dumitrache, University "Politehnica" Bucharest
"Dr. Motit’s "UASCF" flowmeter classification method provides an entirely new perspective, offering deeper and broader insights into existing flow measurement technologies. Of particular relevance to engineering disciplines with an interest in flow measurement technologies, the method facilitates the imagination and potential development of new flow meter types, which could embody multiple desired characteristics of a range of traditional instruments." —Mike Touzin, Head of Market Research & Development, Endress+Hauser Flowtec AG, Switzerland
