PRODUCTION TECHNOLOGY66 PRODUCTION TECHNOLOGY AAC WORLDWIDE %u2022 2.2025Aircrete Europe, 7575 EJ Oldenzaal, The NetherlandsNew Generation Slurry Density Measurement DeviceAccurate slurry density measurement is a cornerstone of quality and efficiency in AAC production, and therefore the measuring device must work reliably to achieve this. Traditional devices, while effective, often struggle with maintaining accuracy under varying production conditions.Enter Aircrete%u2019s new gen,eration Density Measurement Device (DMD) %u2013 an innovation designed to enhance accuracy and streamline efficiency in AAC production. It features a new bypass concept for slurry density measurement that significantly improves measurement accuracy, while keeping the system constantly cleaned with water. This article explores the key features and benefits of the new DMD and how it addresses longstanding challenges in the industry.New developmentsThe new generation Aircrete DMD introduces significant advancements in measurement accuracy. With its innovative design, the system achieves an impressive accuracy of up to 9 kg/m%u00b3, a substantial improvement over earlier models. This level of precision ensures tighter control over AAC production, directly contributing to the consistency and quality of end products.A key feature of the redesigned DMD system is its water-filled standby mode. Unlike traditional setups where slurry continuously flows through the pipe, the new bypass design only allows slurry to enter the pipe of the DMD during specific intervals for measurement. Between cycles, the pipe of the DMD remains filled with water that serves as a density reference point, enabling automatic recalibration before each cycle. Furthermore, should something go out of order within the system, water density reading will show a significant difference from the actual water density, adhering to more optimized on-demand maintenance.%u00a0%u00a0Advantages of the new systemThe new Aircrete DMD offers several advantages that set it apart from traditional systems. Foremost among these is its high accuracy, ensuring precise density measurements for maintaining consistent product quality in AAC production.
