SITRANS F C MASS 2100 Delta Application Technics relies on a Siemens flowmeter to optimize silicone dosing operations The customer Based in Ophasselt, Belgium, Delta Application Technics specializes in the design and manufacture of application machinery and dosing installations for pasty, sludgy liquids such as silicone. Delta Application Technics provides complete solutions, from inception all the way through construction, purchase, installation, start-up and technical support in each production facility. The challenge Silicone, used to manufacture medical bandages, is an expensive product with very demanding requirements. Production of silicone involves high-accuracy dosing as well as mixing extremely precise quantities of very viscous liquid. Operators often spend 1 to 2 hours each day just measuring, recording and adjusting the process. Delta Application Technics recently determined that the accuracy of their existing machines for silicone mixing and small-quantity dosing on textiles was no longer suited to their requirements. According to Jacques Coppens, managing director of Delta Application Technics, “Silicones are thixotropic, which means they are thick and viscous at rest, and can change state when kinetic energy is applied. The manual adaptation and weighting system used previously to control product quality resulted in shifts of up to 15%. Given the high cost of silicone, any offset turned out to be very expensive.” www.siemens.com/flow The case at a glance Region: Belgium Industry: Machine building Customer: Delta Application Technics Challenge: Improve the efficiency of the silicone production process by outfitting new machines with highperformance flow instrumentation to guarantee constant supervision with less than 5% shift Product: SITRANS F C MASS 2100 DI 15 Main benefits • Single-tube construction • Limited pressure loss • Very high accuracy (≤ 0.1% of flow rate) • Wide turndown range (500:1) • Market’s thickest tube wall To improve the efficiency of the silicone production process, Delta Application Technics designed new machines that guarantee constant supervision with less than 5% shift. To accomplish this difficult task, the company sought a high-accuracy Coriolis mass flowmeter to obtain automatic measurements and record production values. The success of our projects depends on the availability and quality of the components, and on the equipment used,” Mr. Coppens explained. “In order to optimize flow measurement, we compared the technical specifications of various mass flowmeters from different suppliers.” The solution Siemens volunteered to participate in the project and suggested the SITRANS F C MASS 2100 DI 15 Coriolis flowmeter. After careful consideration, the Research and Development department at Delta Application Technics concluded that the Siemens solution would be the ideal choice for this particular application. The MASS 2100 offers the advantage of being equipped with a graduated tube: a single-piece curved tube free of any reducer, flow distributor or internal seams. Despite the high viscosity of the liquid being measured (approximately 40,000 mPa•s) and slow flow within the pipe, the MASS 2100 results in only limited pressure loss and guarantees outstanding measurement accuracy of ≤ 0.1% of flow rate. “The results are impressive,” Mr. Coppens continued. “Thanks to the SITRANS F C MASS 2100 flowmeter, with installation and fine-tuning by Delta Application Technics, measurement tolerance is better than 1%.” At the same time, the machines are now capable of determining the quantity of silicone (gr) for each ingredient injected, along with the pump velocity and the pressure, density and temperature of silicones employed. This results in optimum traceability of the production process. According to Mr. Coppens, “Once again, Siemens made the difference as a valuable business partner, offering extensive experience and a user-friendly approach.” About the product The SITRANS F C MASS 2100 Coriolis flow sensor in sizes DI 3-40 is suitable for accurate mass flow measurement of all types of liquids and gases. The full-bore design with a uniform internal diameter throughout the entire sensor results in lower pressure loss, while the single-tube construction offers optimal hygiene, safety and CIP cleanability. The sensor is also characterized by a wide turndown range greater than 500:1 and the market’s thickest tube wall to ensure highest integrity. “I can’t think of many other equipment suppliers who are so actively willing to find a suitable solution to our customers’ requirements,” said Mr. Coppens. “The Siemens meter was a perfect match for our needs.” Siemens A/S Flow Instruments DK-6430 NORDBORG Headquarters: Siemens A/S DK-2750 BALLERUP Subject to change without prior notice Printed in Denmark © Siemens AG 2014 The information provided in this flyer contains merely general descriptions or characteristics of performance which in case of actual use do not always apply as described or which may change as a result of further development of the products.
