This article will define a business case for achieving significant rotating equipment maintenance and energy cost reduction at industrial and municipal facilities.

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.

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.

An automated monitor provides a live, continuous picture of exactly what is happening inside a turbine for protection, prediction, performance monitoring, and integration of the data with process control.

As a public water provider, Loudon Water, a water and wastewater authority in Loudon, Va., must be able to supply water to meet the community's needs.

In my experience, there are three types of maintenance philosophy regarding vibration programs: No philosophy at all, utmost attention with zeal, attention to particularly problematic units

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.

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.

Introduced in August 2008, the Retroflo RPC_2000 Pump Control System was designed to control pump stations as a whole, rather than just the individual components within them. Through continuous dynamic monitoring of the characteristics through a range of wet well levels and pump speeds, the system uses the full range of pumping data available to optimize performance. It can be retrofitted to existing stations or installed in new stations.

Beating occurs when two dynamic excitation sources (forces) are close together in frequency, and a pathway allows the two excitation forces to transfer to each other. The beating effect results because the frequencies are so close to each other that the waveforms alternately reinforce each other at some times and cancel each other at other times. When the vibration from each source adds constructively, the vibration increases. When the vibration adds destructively, the vibration decreases.
