ROBERT P. BENEDICT is a Fellow Mechanical Engineer with the Westinghouse Electric Corporation, and Adjunct Professor of Mechanical Engineering at Drexel University. After serving as a fighterbomber pilot in the CBI Theater from 1942 to 1946, he received his BME from Rensselaer Polytechnic Institute in 1951, and his MS from Cornell University in 1954. He has done additional graduate work at the University of Pennsylvania. Mr. Benedict has written over 80 technical articles and is the coauthor of two books: Generalized Gas Dynamics(1966); and Specific Losses in Flow Systems (1966). He is editor of ASTM Special Technical Publications 470, 470A, and 470B on Thermocouples (1971, 1974, and 1981). He is the author of the texts: Fundamentals of Pipe Flow (1980); and Fundamentals of Gas Dynamics (1983). He has written two nontechnical books: Journey Away From God (1971); and The Christian Connection (1984). He is past Chairman of the ASME Research Committee on Temperature Measurement; Chairman of the ASTM Monograph Committee on Thermocouples; Member of the ASME Fluid Meters Research Committee; Chairman of ASME PTC–19 Committee on Instruments and Apparatus, Chairman of ASME PTC 19.1 Committee on Measurement Uncertainty, and Chairman of ASME PTC 19.3.1 Committee on Thermowells. He is a Fellow of ASTM and a Fellow of ASME.

The determination of machinery performance depends on an engineer′s understanding of measurement theory and technique. This self–contained guide to the measurement of temperature, pressure, and flow rate presents the latest standards and industrial practices. It shows how measurement techniques were developed and then applies them to many practical cases through completely worked–out numerical examples. The book deals with all types of sensors and transducers, detailing construction, installation, supporting electronic circuitry, calibration, response time, and recovery factor for each type of sensor. This Third Edition incorporates important changes that have occurred during the past decade. It treats revisions in the International Practical Temperature Scale that have affected all thermometry. New thermocouple reference tables that correspond to standard equations issued by the National Bureau of Standards are given. Other new materials include: thermocouple analysis; temperature response; pressure tap errors; ASME discharge coefficients; and expansion factors. The chapter on measurement uncertainties and statistics has been completely revised in accord with the latest national standards because of the increasing importance of determining Best Values and Confidence Intervals. Numerous tables and graphs provide a wealth of supporting data never before assembled in so concise a form. Engineers, physicists, chemists, technicians, and students will find this a thorough review of fundamentals and techniques for measuring temperature, pressure, and flow rate.
