Fundamentals of Reaction Flowmeters

This book is the first one that presents both the new elaborated method of the flow measurement, named by the author the "Flow Measurement Based on Reaction Force", including its specific "reaction measurement system", which ensures its practical implementation, and the new basic types of flowmeters, configured according to it, named "reaction flowmeters". These achievements were the result of the first implementation, in the last two years, of the Unitary Synthesis and Design Method of Flowmeters (European Patent EN the 3364159, granted in 2020).

Due to its universality and flexibility, the "Flow Measurement Based on Reaction Force" keeps the same configuration of the reaction measurement system for the design of any new basic types of reaction flowmeters.

The book presents the reaction flowmeters by following the logical sequence of their structural (implicitly functioning) evolution, which rendered the logical systematic way followed for their configuration. The book details successively (main analytical, constructive, and functional features) the individual (single) reaction flowmeters, configured both without and with moving parts, respectively, the specific connections of two single reaction flowmeters, named "extended reaction flowmeters" and the bypass type reaction flowmeters. All of these flowmeters can be used for both liquids and gases.

Presenting the practical results and using the knowledge of the unitary bases of the flowmeters, identified by the previous book, Unitary Analysis, Synthesis, and Classification of Flow Meters (2018), this new publication is written for all specialists in the field of flow measurement and instrumentation, and especially for flowmeters manufacturers and R&D specialists, in addition to the teaching staff and students at such specialized, technical, and high-level universities.

The book is also an efficient tool for predictable design of new types of reaction flowmeters, by following the logical steps (questions) already taken in the configuration of the reaction flowmeters presented, and by diversifying with new answers given to them.

Horia Mihai Moțit is the founding President of the Romanian Technical Standardization Committee for Flow Measurement (1990 - 2006); the founding President of A.A.I.R. -Control and Instrumentation Association of Romania (1990 - present). He received the distinguinshed awards for creativity: the National Prize for Patented Inventions (2nd place) in 1985, the National Prize for Patented Inventions (1st place) in 1987. He has achieved a significant number of patented inventions in the field of new types of industrial flowmeters (then produced in a large number), including the world premiere of the "method for the determination of convertion curves of flow scales of gas variable area flowmeters, by using only water".
