Webinar Recording: How to Calibrate Differential Pressure Flowmeters

In this webinar, experts examine the complexity of testing popular multivariable differential pressure cells that provide a compensated flowmeter output based on differential inches of water (inH2O), static (psia) and temperature (RTD) variables. While this smart instrument can make a very accurate measurement, it is often a “mystery” as to how to properly check and […]

What Are the Benefits of Guided Wave Radar for Level Measurement in Process Industries?

Level is among the most frequently measured process variables in industrial plants. Level readings are used for local indication, process automation and visualization in control systems. Additionally, they are crucial for managing inventory and enforcing safety limits for overfill, leak detection or dry-run protection of pumps. Other applications range from automated ordering systems, to communicating […]

Design of a Self-Tuning Regulator for Temperature Control of a Polymerization Reactor

Abstract: The temperature control of a polymerization reactor described by Chylla and Haase, a control engineering benchmark problem, is used to illustrate the potential of adaptive control design by employing a self-tuning regulator concept. In the benchmark scenario, the operation of the reactor must be guaranteed under various disturbing influences, e.g., changing ambient temperatures or impurity […]
