This Dictionary of Weighing Terms is a comprehensive practical
guide to the terminology of weighing for all users of weighing
instruments in industry and science. It explains more than 1000
terms of weighing technology and related areas; numerous
illustrations assist understanding. The Dictionary of Weighing
Terms is a joint work of the German Federal Institute of Physics
and Metrology (PTB) and METTLER TOLEDO, the weighing instruments
manufacturer. Special thanks go to Peter Brandes, Michael Denzel,
and Dr. Oliver Mack of PTB, and to Richard Davis of BIPM, who with
their technical knowledge have contributed to the success of this
work. The Dictionary contains terms from the following fields:
fundamentals of weighing, application and use of weighing
instruments, international standards, legal requirements for
weighing instruments, weighing accuracy. An index facilitates rapid
location of the required term. The authors welcome suggestions and
corrections at www.mt.com/w eighing-terms. Braunschweig (DE) and
Greifensee (CH), The Authors Summer 2009 Foreword Since its
founding in 1875, the International Bureau of Weights and Measures
(BIPM) has had a unique role in mass metrology. The definition of
the kilogram depends on an artefact conserved and used within our
laboratories. The mass embodied in this - tefact defines the
kilogram, and this information is disseminated throughout the world
to promote uniformity of measurements. Although the definition of
the kilogram may change in the re- tively near future, reflecting
the success of new technologies and new requirements, the task of
ensuring world-wide uniformity of mass measurements will remain.
In this book on Fundamentals of Mass Determination, the definition
and dissemination of units of mass is explained, starting with an
introduction to metrology and mass determination. Establishing a
mass scale requires corresponding mass standards and mass
comparators. The metrological requirements for weighing
instruments, weight pieces, and measuring conditions are explained
and discussed based on international directives and applicable
legal regulations. International directives and institutions are
striving towards the worldwide uniform implementation of these
requirements. Processes used to determine density and volume are
described to the extent that they apply to mass determination.
Calculating measurement uncertainty entails taking into
consideration the effect of influence variables on mass
determination. An overview of this topic is provided to make it
easier to determine and specify measurement uncertainty in
practice, while additional information in the form of tables,
illustrations, and literature references allow the reader to study
mass metrology further.

Providing the first comprehensive treatment, this book covers all
aspects of the laser Doppler and phase Doppler measurement
techniques, including light scattering from small particles,
fundamental optics, system design, signal and data processing,
tracer particle generation, and applications in single and
two-phase flows. The book is intended as both a reference book for
more experienced users as well as an instructional book for
students. It provides ample material as a basis for a lecture
course on the subject and represents one of the most comprehensive
treatments of the phase Doppler technique to date. The book will
serve as a valuable reference book in any fluid mechanics
laboratory where the laser Doppler or phase Doppler techniques are
used. This work reflects the authors' long practical experience in
the development of the techniques and equipment, as the many
examples confirm.
