Flow Measurements

Flow is arguably the hardest process variable to measure well.

An orifice plate is only a metal plate with a hole in the middle - and getting a defensible number out of it takes the right beta ratio, the right straight-run, the right compensation, and a square root nobody may read raw. Meanwhile the same flow loop may feed control, billing, and safety at once, so a measurement that is merely acceptable is often not acceptable at all.

Flow Measurements: From Orifice Plates to Coriolis Meters gives instrumentation and automation engineers one working reference for the entire subject.

Inside the book

• Principles first: Bernoulli's equation, the differential-pressure family, and the flow equations derived from them
• The complete DP toolbox: orifice plates, venturi, nozzles, V-cone, wedge, pitot and annubar elements, laminar flowmeters, installation rules, and high-accuracy compensation
• Every other family explained from first principles: rotameters, weirs and flumes, turbine, vortex, magnetic, ultrasonic, optical, and positive displacement meters
• True mass flow: Coriolis meters, thermal mass meters, weighfeeders, and change-of-quantity methods
• Standardized volumetric flow, custody transfer, and the AGA/API equations for gas and liquid fiscal measurement
• A complete selection method that matches the meter to the process instead of to the brochure

Built for use, not for the shelf: dozens of worked examples with step-by-step solutions, review questions in every chapter, a complete Formula Quick Reference, glossary, and standards acknowledgment. Units are given in both SI and US customary form throughout.

If you select, size, install, commission, or maintain flow instrumentation, this book belongs on your desk.
