The use of wireless technology in industrial automation systems offers a number of potential benefits, from the obvious cost reduction brought about by the elimination of wiring to the availability of better plant information, improved productivity and better asset management.05/15/2013
Without measurement there is no control. As with any type of measurement, results need to be expressed in a defined and clear way to allow everyone to interpret and apply those results correctly. Accurate measurements and good measurement practices are essential in industrial automation and process environments, as they have a direct effect on the success of the desired outcome. Pressure, the measure of a force on a specified area, is a straightforward concept, however, depending on the application, there are many different ways of interpreting the force measurement. This white paper will identify the various units of pressure measurement, while discussing when and why certain pressure measurements are used in specific applications.07/10/2013

Produced water refers to any water brought up to the surface during oil and gas production, typically as the result of drilling, exploration and hydraulic fracturing. Before disposing or reusing the water, it must be treated to extract hydrocarbons and satisfy environmental code regulations.04/16/2013

Understanding the accuracy of a given flowmeter is an important field but it can also be misleading as different specifications are used to explain how accurate a flowmeter measurement actually measures. This paper discusses the different specifications and interprets the impact of them.
Why deal with accuracy?
The reasons for dealing with flowmeter accuracy specifications are many-folded. One important reason is from an economical point of view. The more accurate a flowmeter can measure, the more money you will save as the medium is measured with only very little inaccurately.
Another reason is in terms of dosing, where a given amount of a medium is added. This must be done with a high level of precision and the accuracy is thus important in order to dose correctly. This is critical in certain industries such as in pharma or chemical.
A third reason is in terms of billing purposes. By performing with good accuracy, you know exactly how much fluid flows into the process. Thereby, you are able to determine the right price of the product and thereby bill the customers correctly.
Therefore, knowing how much that flows through your system is paramount in order to make a profitable and solid business. You need to rely on a precise measurement with good accuracy. However, good accuracy must be obtained not only in one measurement, but in all measurements independent of the time.01/21/2013
This paper covers the importance of securing automation devices for access internally on an Intranet, or externally over the Internet. Choosing an Ethernet Fieldbus offers the competitive advantage of speed, flexibility and accessibility though steps should be taken to secure automation devices and any associated programming workstations and servers. This paper seeks to educate the Controls Engineer on security strategies, technologies and options available.02/13/2013

The current loop is probably one of the most underestimated data transmission and control method. It's so simple that we tend to ignore it in favor of more complex and sophisticated methods.04/24/2013
Sensors used for temperature monitoring and data acquisition can be quite varied. Applications ranging from simple room temperature monitoring to highly sophisticated batch process control can all be highly dependent on obtaining accurate temperature readings. The primary types of sensors used for this purpose are resistance temperature detectors (RTDs), thermocouples, integrated circuit temperature detectors (ICTDs), thermistors, and infrared sensors.05/15/2013
When a storage facility's tank level rises above safe limits, a logic solver that is part of a Safety Instrumented System (SIS) initiates final elements to restore the process to a safe state. This can include shutting off input feeds to the tank by isolating the pump and closing the input valve. This white paper explores the possibilities available to SIS designers of tank overfill protection systems when using a logic solver. It includes examples of system topographies and their associated Safety Integrity Level (SIL) calculations.12/05/2013
