Monitoring & metering In remote locations, communications may be


slow, intermittent or unreliable. The RTU is the device at the edge, sitting between the control room and the field instruments, that provides a low latency response to changing site conditions as well as performing data filtering. The RTU ensures that only key, critical


information is passed via the narrow communications links, minimising data throughput but maximising information throughput. Within the downstream sector, refineries operate 24/7, which means firms need RTU systems that are robust, secure, reliable and flexible enough to be able to manage and monitor extensive pipeline networks. RTUs are integrated with sensors across these sites and provide data to the SCADA system. Working the other way, RTUs can receive


commands from the supervisory system and transmit them to the end devices as well as retaining an ability to act autonomously. RTUs can do this over large and remote pipeline networks, handling the data acquisition portion of SCADA, providing early warning of impending issues - such as a rise in temperature of a holding tank or decreased pressure in a pipe - avoiding asset failure, and potential environmental incidents. Pipelines are one of the safest and most


effective ways to transport oil and gas. But, with thousands of miles to cover across some of the world’s harshest environments, monitoring performance and condition can be challenging, to say the least. RTUs offer one solution to this challenge - collecting, reporting and acting on critical data even in extreme and remote conditions.

Fluorescence spectroMeter supports developMent oF novel Fluorophores


H


ORIBA UK has announced the first UK installation of its Fluorolog-QM modular research-grade fluorescence


spectrometer, the world’s highest- performance fluorescence analyser. The spectrometer will form an integral part of research into novel fluorophores by Dr Marc Etherington of Northumbria University. His team is opening up new scientific understanding of fluorophores in order to offer light-based solutions to real-world issues, including the development of new materials to reduce the energy consumption of household devices. Dr Etherington, a vice-chancellor’s senior


research fellow in the Department of Mathematics, Physics and Electrical Engineering at Northumbria University, aims to use the chemistry behind the blue glow of tonic water to modify and improve other materials to become the next generation of efficient light- emitting compounds. These compounds can then be used to reduce the energy use of displays that are used in phones and TVs. HORIBA’s Fluorolog-QM spectrometer


will be a key enabler of this work, providing a flexible spectroscopic platform for high-sensitivity fluorescence analysis and photoluminescence quantum yield measurements. Dr Etherington says: “Most people


associate science with a lab full of brightly coloured liquids and powders. I am personally interested in those that are bright, colourful and glow in the dark! The Fluorolog-QM will be the flagship for understanding why these glow and what colour they are in a measurable and quantifiable way. It will provide the crucial first step on a pathway to more efficient phone screens and displays. I’m looking

forward to working closely with HORIBA scientists to harness the full power of the Fluorolog-QM for this research.” The Fluorolog-QM is the latest generation


modular spectrofluorometer from HORIBA, built on many decades of experience. It layers innovation onto the historical excellence of the Fluorolog platform, resulting in the highest-performance fluorescence analyser in the world. “It’s very exciting to see our first UK


Fluorolog-QM helping to support research into next-generation displays that can help reduce power consumption. Devices such as laptops, tablets and smart phones are growing in number every day, so it is vital that we do everything we can to minimise their environmental impact,” says Dr Simon FitzGerald, technical manager at HORIBA UK. “The Fluorolog-QM is an ideal partner for


Dr Etherington in his research for improved display technology. It has a unique optical design that ensures the highest possible sensitivity, suitable for analysing the very weakest fluorescence and characterising the most subtle of spectral changes. As Dr Etherington’s research progresses and forges new paths, so will the Fluorolog-QM be able to expand its capabilities,” adds Dr FitzGerald. This installation is the latest of many by


HORIBA UK over the last few months, with new deliveries across its wide portfolio of analytical and measurement systems. HORIBA has long and well-established collaborations with the academic community and supports scientific research, not only through its provision of high-performance technology, but also through partnership and support.
