Fluid Flow Measurement


Book Description

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







Orifice Plates and Venturi Tubes


Book Description

This book gives the background to differential-pressure flow measurement and goes through the requirements explaining the reason for them. For those who want to use an orifice plate or a Venturi tube the standard ISO 5167 and its associated Technical Reports give the instructions required. However, they rarely tell the users why they should follow certain instructions. This book helps users of the ISO standards for orifice plates and Venturi tubes to understand the reasons why the standards are as they are, to apply them effectively, and to understand the consequences of deviations from the standards.




Flow Measurement Handbook


Book Description

Practical, comprehensive advice on the design, operation, and performance of flowmeters.







Capnography


Book Description

In recent years capnography has gained a foothold in the medical field and is fast becoming a standard of care in anaesthesiology and critical care medicine. In addition, newer applications have emerged which have expanded the utility of capnographs in a number of medical disciplines. This new edition of the definitive text on capnography reviews every aspect of this valuable diagnostic technique. An introductory section summarises the basic physiology of carbon dioxide generation and transport in the body. A technical section describes how the instruments work, and a comprehensive clinical section reviews the use of capnography to diagnose a wide range of clinical disorders. Edited by the world experts in the technique, and with over 40 specialist contributors, Capnography, second edition, is the most comprehensive review available on the application of capnography in health care.




Flow Measurement Handbook


Book Description

Flow Measurement Handbook is a reference for engineers on flow measurement techniques and instruments. It strikes a balance between laboratory ideas and the realities of field experience and provides practical advice on design, operation and performance of flowmeters. It begins with a review of essentials: accuracy, flow, selection and calibration methods. Each chapter is then devoted to a flowmeter class and includes information on design, application installation, calibration and operation. Among the flowmeters discussed are differential pressure devices such as orifice and Venturi, volumetric flowmeters such as positive displacement, turbine, vortex, electromagnetic, magnetic resonance, ultrasonic, acoustic, multiphase flowmeters and mass meters, such as thermal and Coriolis. There are also chapters on probes, verification and remote data access.




Measurement of Gas and Liquids by Orifice Meter


Book Description

This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1922 edition. Excerpt: ...and the differential increased from 16 inches to 30 inches without any change in the valve C, consequently without any increase whatever in the amount of steam passing through the orifice. After the compressor was started the differential reading again increased without any increase in the amount of steam passing through the orifice. Inasmuch as the increase of differential was not due to an increased flow of steam, the effect was due to the pulsation occasioned by the opening and closing of the slide valves of the generator and compressor, both of them being reciprocating units. It is noted that prior to the test when the machines were not operating that the differential arm remained at zero when there was no steam passing through the orifice, and that after valve C was closed, when there was no steam passing through the orifice, that a differential pressure of approximately 9 inches of water was recorded, due to pulsation only. This differential continued as long as the generator and compressor operated at a uniform speed. The static pen arm in previous tests vibrated over a range of 10 to 15 Ib. with a frequency of the opening and closing of the valves of the reciprocating units when they were operating. To lessen this vibration a dash pot was attached to a static pen arm producing the smooth lines as shown. The effect of partially closing the valves on the gauge lines also produced a smooth pressure reading but gave erratic differential readings. In all cases when the gauge line valves were fully opened the differential reading was very uniform without any appreciable vibration. The weight of steam passing the orifice checked with a differential reading of 16 inches for the total period of the test, so that the flow corresponded to...




Transmission Pipeline Calculations and Simulations Manual


Book Description

Transmission Pipeline Calculations and Simulations Manual is a valuable time- and money-saving tool to quickly pinpoint the essential formulae, equations, and calculations needed for transmission pipeline routing and construction decisions. The manual's three-part treatment starts with gas and petroleum data tables, followed by self-contained chapters concerning applications. Case studies at the end of each chapter provide practical experience for problem solving. Topics in this book include pressure and temperature profile of natural gas pipelines, how to size pipelines for specified flow rate and pressure limitations, and calculating the locations and HP of compressor stations and pumping stations on long distance pipelines. - Case studies are based on the author's personal field experiences - Component to system level coverage - Save time and money designing pipe routes well - Design and verify piping systems before going to the field - Increase design accuracy and systems effectiveness
