Industrial Pressure, Level, and Density Measurement

Industrial Pressure, Level, and Density Measurement is a practical, application-focused guide for technicians, engineers and students. Written clearly with real-world examples, this book begins with measurement fundamentals and explains how instruments convert physical quantities (such as pressure, level and density) into useful readings. It then covers pressure gauges, calibration principles and common pressure transducers, illustrating how accuracy, repeatability and calibration are established and maintained.

This Second Edition discusses modern transmitters and communication systems, including HART, Foundation Fieldbus and wireless options, and explains how digital transmitters improve diagnostics and system integration. Various level measurement techniques are explored, ranging from dipsticks and floats to ultrasonic, radar (both non-contact and guided-wave), capacitance, nuclear and hydrostatic head methods. Practical installation tips, such as managing turbulence, foam, coatings or solids, are also provided.

Finally, the text covers density measurement, hydrostatic tank gauging (HTG) and instrument selection and maintenance. It emphasizes selecting the appropriate technology for a specific process, considering environmental limitations, accuracy requirements and ownership costs. This is a practical, hands-on guide for anyone working with industrial measurement systems.
