Back in the old days, level control had little or nothing to do with saving energy. In fact, it was often a necessary evil. Today, that is no longer true - the VFD offers the potential for power savings in lift station applications that range from a few hundred gallons per minute to those that have to move thousands of gallons each minute.
Effective and secure cellular communications for remote data acquisition
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.
A recent marketing survey found that 84.0 percent of satisfied customers would "jump ship" for a better deal if an opportunity arose. With markets becoming increasingly globalized, customer retention has become a critical part of business strategy. Companies need to ask themselves: What reason can I give this customer to stay, even if my competitor offers a cheaper price? The keys lie in keeping customers loyal to brands and products and ensuring a consistently outstanding customer experience.
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.
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.
Variable frequency drive technology is more efficient and accurate, which leads to increased energy savings. Advancements in capacitors and direct current (DC) link reactors, IGBTs, heat management, processing power and measuring technology are all enabling the development of solutions to problems that were not even recognized earlier. Additionally, new and advanced algorithms affect energy efficiency.
Lift stations can be difficult and costly to monitor, especially when the stations are located in remote areas.

Packaged pump systems are gaining popularity due to their space saving design, simplified installation, single source responsibility and advanced control options with communication ability.
Use of disposable components in product downstream processing and final fill operations is increasing as technology improves for performing these steps in a single-use mode. There is a high demand for systems that support single-use purification, formulation and filling operations.
In recent years, adjustable frequency AC drives have become increasingly popular as they provide an efficient, direct method of controlling the speed of the most rugged and reliable of prime movers, the squirrel cage motor. They provide a spectrum of benefits for a broad range of applications.
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.
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.
Many items must be considered when designing pump station control systems with power requirements, level control method and control panel location often among the most important.

In this multi-part series, we will investigate several aspects of centrifugal pump efficiency.
First of Five Parts
Since the original publication of this draft standard in the January 2008 issue of Pumps & Systems, I have received feedback, encouragement, numerous questions and criticism. The draft listed three basic levels of repair.
The McGraw-Hill scientific dictionary [5] states that a volute is "a spiral casing for a centrifugal pump... designed so that speed will be converted to pressure."
