Red Dot Award for new ultrasonic level transmitter

ABB has won a Red Dot Award for the de- sign of its new ultrasonic level transmitter. The award was presented in recognition of an innovative product which increases accuracy and optimises performance in in- dustrial water processes. ABB’s LST200 ultrasonic level transmitter was awarded best in category for physical

Analytics Division added: “To win a product design award of such repute is an honour. When developing the LST200 we focused on building in design and technical excel- lence throughout to create a product that features an intu- itive user experience and powerful industrial capabilities with the overall aim of making measurement easy.” The smart ultrasonic level transmitter is used to meas- ure distance between one object and another by estab- lishing the time between emission and reception. It can be used in various industrial environments but has been designed especially for water and wastewater treatment applications. The design is focused on simple operation and reliability and the instrument is modular, lending it- self to ease of installation, maintenance and upgrading. A built-in interference filter ensures that information ob- tained from the sensor can be used and analysed easily. Innovative features include the adaptive intelligent algorithms based on long-term experience data and the inclusion of the ABB Ability™ Field Information Manager software for the PC, which improves customer configuration efficiency. Using an ultra-stable algorithm, the device can detect environmental changes including temperature, disturbance, measuring distance and signal strength. It then automatically compensates for the variations to keep the device performing at its best. the system can be expanded by several sampling points at low cost. Additional sensor modules can be used for flexible measuring of all relevant water parameters and thus increase process reliability. Like all sensor cubes, the iron sensor can be easily integrated into a Bürkert Online Analysis System – for example, as a robust IP65 Type 8906 control cabinet solution. The water analysis in the compact control cabinet is then customised to meet the user’s needs and includes pH value, chlorine and chlorine dioxide, ORP value, turbidity and conductivity measurements, all in addition to iron. All sensors are either maintenance- free or have long maintenance intervals and can thus be operated in a resource-saving way. The iron analyser determines the iron content in the range from 0 to 2 mg/l; larger detection ranges are available on request. To do this, process water is automatically sampled in cycles at up to four different sampling points and measured with the sensor by means of flow injection analysis. Rinsing, sampling, adding of reagent, mixing and photometric analysis run automatically. The results can be stored in the system or on the higher-level PLC using a data logger.

as well as technical design. The transmitter is particu- larly recognised for solving the surface condensation challenge often faced by plant owners, where a build-up of water has typically affected the accuracy of essential plant readings. The LST200 uses new generation, active surface technology – known as a ‘lotus effect’ – where the liquid will drop off before it pools into larger drops that could then cause problems, and thus offers a technically effective and cost-effective solution. The Red Dot Award is highly regarded as an interna- tional design prize. Initially presented in 1955, today the awards programme receives more than 15 000 submis- sions annually from over 70 countries around the world. Of the award winning ABB ultrasonic level trans- mitter, the Red Dot Awards jury said: “This robust level gauge impresses with a simplicity that has been thought through down to the last detail. It presents itself as a proven means of ensuring efficiency and reliability.” Jacques Mulbert, President of ABB’s Measurement & It is quite time consuming to check the iron content in drinking water manually, on a constant basis. The Bürkert Online Analysis System with the MS06 iron analyser for photometric iron measurement does this fully automatically, includes several measuring points and allows for long maintenance intervals. The continuous monitoring of important quality parameters is as essential for drinking water procurement and water production in the food and pharmaceutical industries as it is for seawater desalination or wastewater treatment. For many applications, the iron content in water is an essential measured value – iron causes deposits, turbidity or can affect the taste of food. Thus, the water with a high iron content is automatically filtered, but the purified water is then usually tested manually by taking a sample on site.
