This municipal water system evaluated the cost of upgrading their existing SCADA software and decided it was time to consider replacements. After much research, it became clear that not only was it possible to get all the features they were missing; they could also do most of the configuration in-house.

To achieve a sustainable future, the green movement demands increased energy efficiency and conservation. Here is a look at how these changes will impact the water industry and its use of pumps and controls.

Monitoring vibration—a valuable tool in predictive/preventive maintenance programs

Gulf Chemical & Metallurgical Corporation (Freeport, Texas), a subsidiary of the Eramet Group, is a recycler of spent petroleum catalysts and a leading producer of ferroalloys. The company applies hydrometallurgical and pyrometallurgical operations to recover molybdenum, vanadium, nickel and cobalt for reuse by major catalyst producers and steel manufacturers. Embarking on the road to improved equipment reliability represents a key aspect of a concerted strategic initiative for Gulf Chemical. The introduction of wireless technology and additional support has yielded successful outcomes for its facility.

Find the right flow meter for your process and plant.

Industry analysts predict that in the near future, most motors will be controlled by variable frequency drives. Here are the reasons why.

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

Low-cost additions help bottle maker manage compressed air use and energy costs on a shoestring.

A sewage lift pump that pumps millions of gallons per day simply can't go down. To prevent this from happening, this pair of electricians went about testing some new electrical systems for those pumps with a new insulation multimeter.

Released in January 2010, the SDT270 Ultrasonic Detector, in conjunction with its powerful database software, gives the earliest indication of bearing re-lubrication requirements, bearing failure, and pump cavitation.

While driving a car with the gas pedal to the floor and then controlling your speed using the brake is obviously inefficient, many facilities use the approach for pump control. Flow control with throt­tling or restrictive devices sacrifices energy efficiency and results in unnecessary costs. However, with an understanding of basic principles, an analysis of the specific application, information about available control solutions and evaluation of technologically advanced equipment, facilities can make a quantum leap in improving the efficiency and econ­omy of pumping operations. pump efficiency

Explore the current condition of SCADA reports and some new technology that will improve the quality of those reports.

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.

Pressure gauges are a versatile way to monitor pump operation.

Dynamic pressure sensors and accelerometers are frequently used for precision measurements in oil, gas and petrochemical industries, as well as for natural gas supply monitoring applications. The development of piezoelectric sensor technology with integral charge amplifier, as well as the development of high temperature charge output designs, has been especially important for dynamic sensing applications. To truly understand the benefits of this technology, one must first review the evolution of this type of sensing.

Choosing the right differential pressure flow meter for an application can be challenging. This article outlines the considerations and trade-offs in selecting the optimal technology.

Precision laser alignment can help end users avoid multiple problems in wind turbine applications.

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

The next generation solution for variable speed pumping applications are variable frequency drives (VFDs) with integrated advanced pumping software that solves various control applications without the need for a PLC or separate controller.

The second part of this three-part series explores the types of protection applied to specific equipment installed at water and wastewater facilities and some typical criteria used to develop protective settings.
