Abstract
The present invention relates to systems of methods of detecting and measuring inclusions in liquid metals. More particularly, non-metallic inclusions having a conductivity level different from the liquid metal melt are forced to migrate and are collected on a measurement surface using electromagnetic Lorentz forces. The inclusions and their concentrations are detected at the measurement surface using either an electrostatic detection system or an optical detection system.

A method for detecting and measuring inclusions in a fluid comprising the steps:
- forcing the migration of particles in a fluid conductor to a measurement region;
- and
- detecting the particles in the measurement region.
Apparatus for measuring inclusions in a conductive liquid comprising:
- a conductive liquid source;
- an electrode device positioned relative to the liquid that provides a current path in the liquid;
- a current source connected to said electrode device;
- and
- a detection device that detects material in the liquid.
Apparatus for measuring inclusions in a liquid comprising:
- a source of a liquid having inclusions;
- an electrode system positioned to provide a current path in the liquid;
