ing to assist our customers meet their production targets,” he says. “We also look forward to continuing our investment in local skills, which includes supporting 22 graduates – 90% of whom are drawn intoour business after qualifying fromtheir university studies.” Ramsden highlights the importance of theWeirMinerals’Mill CircuitUniversity in providing essential training to staff – help- ing to keep the company and the broader mining industry operating at the highest levels of performance. “The technical ex - perts in our business constantly leverage new technology, applying it to our products to the benefit of our customers,” he says. “The use of 3D scanners, for instance, enhances the capability of our process engineers when they visit customer sites. This enables them to quickly generate the measurements theyneed todevelopquality proposals for productivity solutions.” He is also confident about the prospects for the Middle East, where comminution is the main focus of the company’s offer- ings – serving the considerable demand for infrastructure works in that region. Its local capacity has been further enhanced by the recent unveiling of a newworld class service centre in Dubai in the United Arab Emirates. “This aligns with ourmission to be avail - able wherever and whenever our custom- ers need us,” Ramsden concludes. www.minerals.weir

Contactless and precise volumetric flow measurement GEMÜ, a manufacturer of valves, measurement and control systems, is introducing its new GEMÜ 3040 ultrasonic flowmeter, which can be used to determine conductive and non-conductive volumetric flows of liquids in a contactless process. T he GEMÜ 3040 ultrasonic flowme - ter is distinguished by its suitability for a wide range of nominal sizes (DN 10 to 50), its lack of moving

the important operating parameters can be read directly on the flowmeter and it comes with integrated empty pipemonitoring and a quantitymeasuringdeviceas standard. Inor- der to optimise integration into different ap- plications, all of the standard electrical and mechanical connections are also provided. As sensor systems are also often used in control circuits as part of process auto- mation and monitoring, the GEMÜ 3040 measurement device can be combined with aGEMÜvalve andGEMÜpositioner or pro- cess controller to form a complete pressure control system. With the launch of this ultrasonic flow - meter, GEMÜ is further expanding its prod- uct range of measurement systems. In ad- dition, the GEMÜ C38 SonicLine ultrasonic flowmeter remains available for ultra-pure applications. www.gemu-group.com

parts in the media-wetted area and its in- creased accuracy and reproducibility of mea- surement results. The device can be used to measurebothconductiveandnon-conductive media within a pressure range of 0 to 16 bar withanaccuracyof 2%of the valuemeasured. The flowmeter can be used in a temperature range of between -10 °C and 80 °C. Its high-quality plastic body means that the GEMÜ 3040 can be used for corrosive media, suchas acids andalkalis. Its use incool- ing circuits, chemical processes and water supply projects makes up just a small part of the flowmeter’s diverse areas of application. The illuminated display, which is installed as standard, means that programming can be carried out directly on site. In addition, all

GEMÜ 3040 ultrasonic flowmeters can be used to measure both conductive and non-conductive media within a pressure range of 0 to 16 bar within an accuracy of 2% of the value measured.
