摘要
The present invention provides a fiber fineness value (micronic value) to provide appropriate , also fine mineral fibers (fineness) relates to a measuring device (1) , the device (1) comprises a device (device) (8) for measuring the fineness index , and the fineness index measuring device (8) includes a plurality of , receiving a test piece made of a fiber to a suitable measurement cell (measurement cell) connected to the first orifice (2) (orifice) (3) and , the pressure difference on either side of the test piece (differential pressure) to the device (5) for measuring the and having an associated second orifice (6) , the differential pressure measuring device (5) is adapted to be connected to the fluid flow (fluid flow) generator 10 . The present invention , the fineness index measuring device (8) is characterized in that it includes at least one volume flow meter for fluid passing through the cell (2).
