Storage of coarse bulk materials 
Gravel and grit are required as substratum for road construction and as an admixture in concrete. These materials are stored in large, usually concrete-lined, silos and bunkers. The implemented level measurement technology must meet very tough demands. 
3DLevelScanner for volume and level measurement in gravel and grit silos
Due to the high tractive forces and abrasion, level measurement techniques that contact the medium are unsuitable for this job. The non-contacting APM 3DLevelScannerT mapping sensor, specially developed for such applications, provides an elegant low-cost solution. Not impacted by dust, abrasion, product moisture or filling noise, the instrument carries out measurement reliably in silos or bunkers up to 70 m (230 ft) high. Struts or other obstacles do not interfere or skew the results.document.currentScript.parentNode.insertBefore(s, document.currentScript);
