Flow Measurement

Flow Measurement By Square-edged Orifice Plate Using Corner Tappings deals comprehensively with the subject of flow measurement through pipes by a square edge orifice plate using corner tappings. The object is to present in easily readable and applicable form a consideration of all the many factors involved in accurate measurement, thus enabling readers to appreciate what is involved in good flow metering practice, to design if desired their own installations to predetermined standards of accuracy, and to make reliable assessments of existing installations. The book is organized into four parts. Part 1 discusses basic principles, approved design and installation conditions, and recommended follow-up maintenance for various predetermined standards of accuracy, with special attention given to requirements concerned with the metered fluid, working conditions, orifice design, pipe layout and pipe conditions. Part 2 deals with the practical application of Part I and describes the method of using a Flowmeter Data Sheet specially designed both to ensure that the numerous factors involved in accurate flow measurements are taken into account. Part III consists of a number of representative and well-detailed specimen calculations designed to illustrate and clarify all aspects of the method of calculation advocated in Part II. In Part IV a considerable amount of relevant data on the physical properties of fluids, and many tables, graphs and alignment charts are assembled together for easy reference when making orifice calculations.
