Flow Measurement and Instrumentation: Critical Components for Sustainable Processes

Consumers, industry, and society in general benefit from a commitment to sustainability. This concept is not purely about conservation or “being green.” Sustainability is not about using less, but about using the right or necessary amount—reducing waste in the process. The value of sustainability as a business opportunity is balanced between altruistic ideas related to […]

IoT Is Ready for the Process Industry

In today’s competitive business climate, process plants are looking for ways to quickly reduce costs, improve operations, and comply with regulatory requirements. Addressing these challenges with yesterday’s technologies, while practical, often has unsatisfactory results and does not yield the desired competitive advantage. But there is a technology ready for deployment right now that can address […]

New Applications for Pressure Measurement Technologies

Accurately measuring liquid, gas, and steam pressure is a basic requirement for many industrial processes to operate safely, efficiently, and with optimum quality control. In addition to directly measuring pressure values, pressure measurements can be used to determine or infer flow rates, fluid levels, product density, and other parameters. As a result, many plants rely […]

PID Tuning for Near and True Integrating Processes

The most important loops on vessels and columns typically have a near or true integrating response. A self-regulating process is classified as near integrating if the process time constant is larger than four times the process dead time. The composition, pH, and temperature response of continuous columns tend to have a time constant to dead […]
