Razvlaknjenje taline mineralne volne je kompleksen proces, katerega poznavanje je ključnega pomena pri proizvodnji izolacijskih materialov. Postavili smo preizkuševališče, ki omogoča proučevanje procesa razvlaknjenja. Pomembni vhodni parametri, ki vplivajo na proces, so vrtilna frekvenca koles centr ...

Oznake:
optical measurements;mass flow rate;melt;
This paper presents an optical method and system for contactless measurement of the mass flow rate of melts by digital cameras. The proposed method is based on reconstruction of melt stream geometry and flow velocity calculation by cross correlation, and is very cost-effective due its modest hardwar ...
