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.

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.

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.

Why question the PLC? For many, questioning the application of a PLC to the pump station panel is surprising. After all, the pump station panel was once controlled with a range of relays, timers, and other devices - the exact type of application where the PLC has had such success in industrial automation. pump efficiency

Since municipal codes frequently deal with the most crucial areas of public life-covering the safety of life and property-it is understandable that preference is given to tools and methods that are "tried and true" over ones that are untested. The challenge becomes how to take advantage of new advances in technology while recognizing the importance of maintaining an uncompromising level of safety and security. The answer can lie in close cooperation between officials who champion the integrity of the municipal code system and individuals experienced in the implementation of innovative technologies.

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.

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

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.

With the growth of wind farms, users are turning to condition monitoring and automatic lubrication systems for increased reliability.

Condition-based monitoring (CBM) is a maintenance process where the condition, or “health,” of plant equipment is monitored for the earliest signs of impending failure.
One common definition of balance is when the mass centerline and the rotational centerline of a rotating part are equal.
