  • Wind Energy Production Estimates: Moving Beyond Time Averages

    No need to be a statistician to see that averages are often useful to compare different things. And yet, they often fall short as a true measure of performance. For instance, we use averages to compare the current weather against the climate normals or to get a sense of how our favorite sport team or player is doing. Team (player) statistics are a concise way of combining the scores from many ...

  • Viscous Pumping in Focus

    The performance of a pump is influenced when it handles viscous fluids such as crude oil. For the configuration and design of pumps, this is key. In the industry, pump performance curves are developed by testing with water at temperatures around 25°C and corrected to a specific gravity of one. Engineers use this standard so that they have comparable measurement values around the ...

  • Top 10 Reasons to Choose a Diaphragm Actuated Control Valve

    Every water system typically consists of piping networks that distribute water from a source or storage reservoir to the end users. This frequently requires miles of piping mains along with pumps systems and controls that all have to be monitored and controlled somehow. Whether this control is to regulate pressure, a level or a flow, this usually will require some form of a ...

  • No Place Is Too Far

    The remote location of hydropower stations is often a great challenge when major repair work is necessary. The refurbishment of a large generator in the Scottish Highlands shows how Sulzer finds cost-effective service solutions even in places miles from nowhere. Much of the UK hydroelectric capacity was built during the 1950s. These installations have performed extremely well, especially ...

  • 5 Pieces of equipment needed for the pipe bursting process

    Sewer pipe bursting looks a little bit like magic if you compare it to the traditional methods of sewer replacement. With the use of underground construction equipment, including directional boring equipment, sewer technicians are able to pull a new pipe through the old pipe without digging a hole into the top surface of the ground. The sewer pipe bursting method is the perfect pipe replacement ...

  • Hydraulic Fracturing and the Environment Whitepaper - Analytical and Measuring Instruments

    The recovery of natural gas and oil from untraditional wells is necessary for the economic stability of the United States. Shale gas deposits are deep below the earth’s surface and recovery of gas is expensive and requires millions of gallons of water mixed with chemicals, known as "fracking solution". Most fracking solution stays underground or returns to the surface mixed with formation ...
