There is a tendency to make flow measurement a highly theoretical and technical subject but what most influences quality measurement is the practical application of meters, metering principles, and metering equipment and the use of quality equipment that can continue to function through the years with proper maintenance have the most influence in obtaining quality measurement. This guide provides a review of basic laws and principles, an overview of physical characteristics and behavior of gases and liquids, and a look at the dynamics of flow. The authors examine applications of specific meters, readout and related devices, and proving systems. Practical guidelines for the meter in use, condition of the fluid, details of the entire metering system, installation and operation, and the timing and quality of maintenance are also included. This book is dedicated to condensing and sharing the authors' extensive experience in solving flow measurement problems with design engineers, operating personnel (from top supervisors to the newest testers), academically-based engineers, engineers of the manufacturers of flow meter equipment, worldwide practitioners, theorists, and people just getting into the business. The authors' many years of experience are brought to bear in a thorough review of fluid flow measurement methods and applications Avoids theory and focuses on presentation of practical data for the novice and veteran engineer Useful for a wide range of engineers and technicians (as well as students) in a wide range of industries and applications

This is a definitive guide for engineers to the actual and developing practice in this important area, which is not only essential to those involved in water supply and sewage treatment but also important to those involved in any process industry where fluid flow plays a part. There are numerous benefits, including efficiency, cost saving and product quality, associated with the use of appropriate instrumentation in any industry. The advantages of effective measurement of flow, level and pressure in the water industry also include safety, hygiene and security of supply. Despite similarities with other process industries, the requirements of the water industry are unique in many ways. This book is the first to describe actual and developing practice in this exciting field for application of new instruments and techniques. Traditionally instrumentation used to measure water flows and levels was mechanical, but a new generation of electromechanical and electronic systems are now available. Much of the instrumentation described in this work is common to all process industries, though never before have operational and technical details used in the water industry have been described explicitly. Graham Fowles is Instrumentation, Control and Automation Controller at Severn Trent Water, UK. He has been an instrument engineer for 25 years, and has spent the last 20 years in the water industry. The measurement techniques and instruments he describes are applicable to all stages of the water cycle, including river monitoring, water supply, distribution and metering, and sewage treatment and disposal. The book is a definitive guide for water engineers which will also be of interest to any engineer concerned with fluid flow, such as in the petrochemical and food industries. - Control & Instrumentation, March 1994
