Flow dependency reduction method for fluid soiling level measuring device with particle counting sensor contained in measuring cell using light-blocking principle

摘要

The method has the light beam cross-sectional surface (18) provided by the fluid particle counting sensor in the direction (14) of the fluid flow selected so that it is greater than the light beam cross-sectional surface in the transverse direction at the entry point (22) of the particles (10) suspended in the fluid to the light beam cross-sectional surface. An Independent claim for a device for reducing the fluid flow dependency when measuring the soiling level of a fluid flow is also included.
