Water system operators know the challenges of keeping municipal drinking water consistently and safely chlorinated. Increased safety concerns regarding common disinfectants and mandated chlorine residual targets make maintaining large or small water systems difficult.

Read how WirelessHART can be implemented in large process plants despite the distances needed for the network.

Last month, we ended our discussion of proportional control by saying there are times when P alone cannot provide the accuracy required by a process. Take, for example, a constant pressure booster system under VFD control. If changes in flow and the resulting change in pressure occurred gradually over a long period of time, the VFD could use proportional control to keep pressure constant.

Introduced in June 2010, the VibXpert II (VXP II) has many different uses and functions. The primary use is to extend the lifespan of equipment within a plant or facility using vibration signatures. One of its many applications is detecting bearing faults, either early or pre-existing within the machinery. It can also detect cavitation within pumps.

Traditionally, the primary use of drives has been in applications such as powering pumps, fans and conveyors. While they will continue to be used in these applications, today's end-users have a different approach from that of a decade ago.

The third annual Product Innovation of the Year award was hotly contested again this year. The contest examined products entered into the marketplace between September 1, 2010 and August 31, 2011.

Many reasons for wireless conversion reluctance are resolved with new technology.

Pulsation and water hammer can be limited with proper forethought and equipment.

Variable frequency drive technology is more efficient and accurate, which leads to increased energy savings.

One electrical equipment specialist is relying on a cleaning system to ensure that a variety of stamped and turned parts are thoroughly degreased at their production facility.

One of the first steps in shaft alignment preparation is to make sure that the machines are locked out and tagged out. If equipment is accidentally started while an alignment is being performed, serious injuries could occur.

Changing traditional industry ways of thinking can help usher in the plant of the future.

In only a couple of years, the focus on energy efficiency has gone from blurred to steely-eyed. Green business practice is now a necessity, and organizations must find the best way to transition to this new reality. There are many opinions and approaches on "how we get there," and each one will have its own merits. A journey of a thousand miles starts with a single step, and making the right steps in the beginning will hasten the achievement of energy efficient goals.

Potential to Failure (P-F) curves graphically display the failure time cycle and measurement techniques that can be used to detect asset failures prior to reaching the asset incurring functional failure. Proactive strategies should focus on managing assets high on the P-F curve, or early (P1 to P5) in the failure cycle (Figure 1). The ability to detect failures early in development allows top quartile performers to proactively manage their maintenance programs by understanding the health of their assets. Many companies, however, find it difficult to operate proactively and continually react to assets that reach functional failure with little or no warning.

Applications for electric power and the Smart Grid

The residents of Orlando and nearby communities are more likely to see lightning strike than have their toilets run dry. Extensive high-tech upgrades at Orlando's three advanced wastewater treatment plants, including new automation and control systems, have helped city staff process more sewage and gray water effectively and reliably.

Effective and secure cellular communications for remote data acquisition

Qualified, quality solution providers can resolve many aftermarket problems.

When selecting a pump for variable speed operation, a number of conditions must be evaluated.
