In his preface, the editor describes this volume as a road map to the field of flow measurement. It discusses strategies for problem solving and puts the whole array of types of flowmeters at the reader's disposal. Emphasis is placed on the importance of accuracy in measurements and ways of ensuring accuracy and avoiding equipment damage through correct forecast of operating conditions, flowmeter selection, installation, calibration, and maintenance. Fundamental considerations such as mixed-phase flow, piping effects, and flow conditioning are examined at length. The problem of attaining a meaningful flow signal through linearization, compensation, and totalization is discussed.
