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 […]

Webinar Recording: Benefits of Integrating IIoT-Ready PLC and DCS Platforms

The Industrial Internet of Things (IIoT) has the potential to be the most significant development in automation systems since the introduction of distributed control systems. It offers a wide range of potential uses and benefits.  Specifically, PLCs with IIoT capability can provide a broad range of advantages: Reducing the time and effort for configuration and […]

How to Avoid Common Tuning Mistakes

The proportional, integral, derivative (PID) controller is the common key component of all control loops. Basic control systems depend upon the PID to translate the measurement signals into set points of secondary loop controllers, digital valve controllers, and speed controllers for variable frequency drives. The success of advanced control, such as model predictive control, depends […]

The Good, Bad and Ugly of Thermal Mass Flowmeters

Thermal mass flowmeters can be a relatively inexpensive flowmeter that can handle extremely small flows (e.g., inline 1/16-inch meters) and large flows (e.g., multipoint insertion type in 60 inch ducts). Thermal flowmeters introduce heat into the flow stream and measure how much heat is absorbed using one or more temperature sensors. However, the meter requires […]

Webinar Recording: How Does Low Flow Affect Differential Pressure Flowmeter Calibration?

For flowmeter calibration, the phenomenon of “low flow cut-off” is only associated with differential pressure transmitters with square root extraction—if the square root (flow) calculation is done in the control system (DCS/PLC), then this test approach does not apply. The graphic below illustrates the issue. Some may ask why we are testing the initial point […]

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 […]

Are Parents Out of Touch with Careers in Manufacturing?

There’s plenty of concern about the retiring generation of industrial professionals and the potential shortage of skilled workers needed to fill new jobs created by revolutionary advances in automation and manufacturing technology.  Industry leaders remain hyper-focused on the challenges of encouraging high school and college students to pursue industrial careers. But according to a new […]
