This book is aimed at the busy practitioner who is faced with a flow measurement problem, and requires enough information to assess the advice received from manufacturers and to contribute to discussions with experts. The previous editions of this book have been widely used for over 13 years. In this new edition, the author retains the succinctness of the earlier books by removing material that was of marginal value, and by referring readers who require more detailed information to other resources. This first U.S. edition, published by ASME Press, includes, ASME Code references, which were not included in previous British editions of the book.
