How to Succeed – Part 4

We continue this series with some helpful hints for control system design and implementation. This week we look at ¬†measurement location and selection. Since a control system deals with change, the prevalent theme is how to improve the detection and correction for change. In the coming weeks we will take a look at control valves …

Top Twelve Mistakes in pH System Design

The extreme capability of the pH measurement and the broad spectrum of applications and process conditions create exceptional requirements for electrode design, mixing uniformity, control valve precision, deadtime minimization, nonlinearity compensation, and control strategies. pH loops are often the most challenging loops in the plant. Slight deficiencies in the mechanical, piping, process, measurement, and control …
