In one aspect, a system includes at least one processor configured to identify a digital image of the process station generated during an operation of the process station, identify, in the digital image, a visual indicator of the process station, and analyze the visual indicator to identify a current state of the visual indicator. The at least one processor is further configured to identify configuration data for the process station that defines an expected state of the visual indicator, determine whether the current state deviates from the expected state, and generate indicia representing the identified current state in response to determining that the current state deviates from the expected state.

An apparatus to detect and measure suspended particles in a molten metal where the suspended particles have an associated noise frequency range has in addition to the electrically non-conductive barrier for immersion in the molten-metal, a device to move the molten metal through an orifice in the barrier and electrodes, a time varying excitation source that generates an AC current at a predetermined range of excitation frequency that is out of the predominant noise frequency range to generate an AC signal that is representative of the measure of the suspended particles. A detector detects and quantifies from the measurement AC signal the suspended particles. The detector can be a synchronous detector.
