The top 5 most read articles online, from Sept. 19-25 for Control Engineering, covered level instruments for applications, piezoelectric measuring, PID control and loop tuning fundamentals, motor efficiency standards, and process control simulation benefits. Link to each article below. 

1. How to choose the right level instrument for applications

There are many level measuring techniques, however they need to be the right fit for the application. See the three key constraints to measuring solids in tanks and vessels.

2. Piezoelectric measuring technology benefits 

Piezoelectric sensors have many benefits and are among the key technologies that determine business success for industrial manufacturers.

3. Understanding PID control and loop tuning fundamentals

PID loop tuning may not be a hard science, but it’s not magic either. Here are some tuning tips that work.

4. New regulations will improve energy efficiency beyond existing motor efficiency standards 

While motor efficiency regulations may make the news, many other energy conservation standards are involved in similar rulemaking processes. These new and updated regulations will have a strong affect on the automation industry, particularly for original equipment manufacturers (OEMs) and end users.

5. Process control simulation benefits

Process controls simulation can serve as a powerful and effective tool for training operators and assess safety and environmental risks.

The list was developed using CFE Media's web analytics for stories viewed on, September 19-25, for articles published within the last two months.
