Guided Wave Radar (GWR) transmitters are often favoured devices, as they — unlike traditional mechanical technologies — virtually have no moving parts, reducing maintenance costs and extending operational life. Many GWR installations require a separate instrument chamber, and choosing the right chamber is important for rapid installation, accurate measurements and reliability.

Some people see the glass as half full, some as half empty. Neither approach is inherently bad, it’s just two different ways of looking at things. If a pipe is only 50 percent full, however, and you want to measure flowrate, the problem is more than just one of terminology. As one US utility company found, few instruments can accurately measure flow in a part-full pipe.

Lined pumps are an economical alternative to metallic magnetic drive pumps for a whole series of applications, as the following example from real life shows.

Handling demanding media just got easier: A new pump technology expands the range of applications — A technology that till now was only available for the continuous operation with expensive process pumps makes its debut on the mass market: A new double hose-diaphragm pump provides in-built compressor and bypass flow control for pressure ranges up to 16 bar.

They are green, they grow fast, they are powerful — microalgae are, so to say, small versions of the incredible Hulk. And they have their superhero story, too. Follow us on a trip to a biobased micro-world …

The Sandvik Group’s expertise in sulphur solidification has been well established over many decades and its Rotoform system has now been installed at most of the world’s major refineries. On example is Hellenic Petroleum’s Elefsis refinery near Athens.

A Spanish refinery makes the best of its challenging location with state of the art wireless monitoring — A refinery never stands still: Hundreds of thousands of barrels of oil, fuel and petrochemicals are pumped back and forth each day. With stakes that high, valve monitoring becomes a crucial challenge. But what if the situation calls for a wireless solution? Discover, how process monitoring takes to the airwaves …

Nowadays, the most common way to obtain extremely fine particles from suspensions is a combination of spray drying followed by a subsequent grinding process. The grinding step is necessary because the product from a spray dryer is in the form of an agglomerate. To avoid the need for this two-step process and so reduce equipment costs, Nara has developed a different type of dryer.

At the beginning of the year, a large desalination plant was put into operation on Australia’s Gold Coast. It delivers 125 million liters of drinking water each day, which in this dry region corresponds to 20% of drinking water requirements. For this project, Nijhuis Pompen BV of Winterswijk — part of the Norit Group — delivered and installed 42 pumps. At the customer‘s request, some pumps use condition monitoring, where the vibrations are measured using sensors and measurement modules on the Wago-I/O-System.

Seamless documentation of all process values is required in order to further optimize processes and systems. Previously, far-away systems such as tank farms and pump stations could only be incorporated into the process automation with a large investment or not at all. The GSM network offers a simple solution to this problem if the safety criteria for areas subject to explosion are taken into account.
