Presents, for the first time, the new method, named the "flow measurement reaction method", and the "reaction flow meters", configured by its implementation so far. Systematic detailing of all basic types of reaction flowmeters, according to their presented general classification and following the evolution of their structural and functional complexity. Explores and demonstrates the universal application of "the reaction force method of flow measurement" for configuration of the reaction flowmeters both without and with moving parts, respectively of their specific connections. Unitary, consistent and coherent presentation, in a logical sequence, of all different basic types of reaction flowmeters, following the same manner (basic configuration and operation, functional equations, constructive solutions, main features). The book is 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 the diversification of the answers given to them.

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.
