Yuba County Water Agency in Marysville, Calif., recently chose a wireless system as a solution for a water pump problem. Here are some of benefits they discovered.

Packaged pump systems are gaining popularity due to their space saving design, simplified installation, single source responsibility and advanced control options with communication ability.

As oil prices and gasoline usage have increased, the demands on U.S. oil and gas wells have grown dramatically. In the past, there was a low cost supply from the Middle East, and U.S. oil wells were not used as frequently due to low reservoirs and the energy cost associated with extracting the oil. A large number of U.S. wells were shut down in reaction to high electric costs, low oil prices, the need for monitoring the oil reservoir and machine maintenance. As of 2004, there were just over 800,000 onshore oil wells in the world, with about two-thirds of them in the United States.

In the U.S. industrial sector, motor-driven systems consume 70 percent of all electricity. Motor-driven pumps account for more than 30 percent of that amount-more than any other application. Considering energy and maintenance represent more than 80 percent of total motor life cycle costs, a growing number of system designers, specifying engineers, maintenance professionals and end users are turning to variable speed motor control systems that can save up to 60 percent in energy costs as well as significantly reduce maintenance and equipment costs, improve process control and enhance system reliability.

Vibration monitoring of rotating equipment and analysis of the resulting data are effective ways to evaluate the health of production machinery in order to achieve best maintenance practices, extend equipment longevity, and avoid unplanned shutdowns. Plant equipment seldom fails without giving signals well in advance, so breakdowns can normally be predicted by listening for the warnings and passing that knowledge on to those in a position to prevent such problems.

Production, distribution and refining applications in the oil and gas industry rely heavily on motor-driven pumps and pumping systems. Keeping electric motors driving critical operations at peak performance is vital to ensure maximum profitability.

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.

The details of a mass-based chemical injection system for an application that requires critical dosing of a trace chemical into a continuous flowing fluid.

A successful infrared program involves planning and action. This article outlines steps that will help you implement a thermography program.

Traditional control techniques examine the "running" status and the "not ready" status of the control circuit.

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.

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.

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.
