What is the economic value of a new measuring device in a process plant – a new analyzer, a more accurate flow measurement, an additional temperature or pressure measurement, etc.? Excluding the minimum set of measurements required to safely operate the plant and meet regulatory requirements, how...

Wireless measurements reduce wiring installation and maintenance costs and eliminate electrical noise and ground loops.
A unique resource for process measurement Basic Process Measurements provides a unique resource explaining the industrial measuring devices that gauge such key variables as temperature, pressure, density, level, and flow. With an emphasis on the most commonly installed technologies, this guide...
This testing procedure provides methods of conducting and interpreting field tests on centrifugal pumps with actual pumped fluids. Contents include definitions and descriptions of terms; test planning; instrumentation and measurement methods; test procedure; computation of results; and...
This procedure offers complete methodologies for sampling and measuring particle streams and summarizes methods of particle size analysis. It also lists operating variables to be considered and measured. Although the procedure is intended specifically for particle classification equipment, many of...
To select the proper instrument for process monitoring, one must determine what attribute of the particle system impacts the process or product parameter of concern. Once the size region is identified, it can be tracked in-process, opening up the...
