What is Signal Isolation? - In most processes there are pieces of electronic measurement and control equipment from many different manufacturers. The signals from these instruments are interconnected to each other and to sensors, transducers and output devices connected in the process loop. In any such measurement and control system there are several electrical interfacing problems that are likely to occur, all of which can be solved by incorporating the appropriate isolation between the signals. This excellent article from our sponsor Weidmuller addresses this.
The Expression of Uncertainty and Confidence in Measurement - This is an updated version of the UKAS guide to uncertainty. M3303 gives information on understanding and implementing international requirements for evaluation and reporting of measurement uncertainty. From the United Kingdom Accreditation service.
Fundamentals
Of Gas Measurement -
D. A. Tefankjian - In any field of endeavour for a person to completely
understand the endeavour, he or she must have a knowledge and an understanding
of the fundamentals involved. People can do well in the performance of their
work without knowing the basic principles, but to excel and progress knowledge
of the fundamentals is necessary. This is particularly true if one’s work is
technical in nature - Includes – Units of Measurement, Behaviour of the gas
molecule, property of gases, the gas laws along with the methods and means of
measuring gas

SPECIFIC GRAVITY
Determination
of Specific Gravity of Gases: Fundamentals and Instruments -
Faruk Civan - Specific gravity is one of the basic properties used for
characterization and measurement of gases. Instruments used for determining
specific gravity are called gravitometers. There are also methods by which
specific gravity can be determined indirectly. Accurate determination of
specific gravity is essential for accurate measurement of gas flow rate - from
