Method, system, and sensor device for monitoring foam in vessel

A method for monitoring foam within a vessel, the method comprising:

• detecting movement of a sensor device within the vessel via an accelerometer;
• generating movement data based on the detected movement;
• determining a foam status of the vessel based on the movement data;
• determining the foam status based on the movement data and stored foam models associated with different foam statuses;
• and
• generating the foam models based on controlled state information for one or more controlled states of the vessel, during which the foam status of the vessel is known, and movement data is generated during the one or more controlled states.

A system for monitoring foam within a vessel, the system comprising:

• a sensor device within the vessel, the sensor device comprising an accelerometer for generating movement data based on detected movement of the sensor device;
• a detection module for determining a foam status of the vessel based on the movement data, wherein the detection module determines the foam status based on the movement data and stored foam models associated with different foam statuses;
• and
• a machine learning module for generating the foam models based on controlled state information for one or more controlled states of the vessel, during which the foam status of the vessel is known, and movement data generated during the one or more controlled states, wherein the machine learning module generates the foam models based on the controlled state information and the movement data generated during the one or more controlled states by extracting features of the movement data for each controlled state and classifying the extracted features as being associated with different foam statuses based on the controlled state information.

A method for monitoring foam within a vessel, the method comprising:

• detecting movement of a sensor device within the vessel via an accelerometer;
• generating movement data based on the detected movement;
• determining a foam status of the vessel based on the movement data;
• calibrating the sensor device in one or more controlled states of the vessel for which a known foam status is provided;
• building and storing a foam model that correlates movement data from the accelerometer to respective foam statuses;
• and
• wherein determining the foam status of the vessel comprises comparing the movement data generated during normal operation of the vessel to the stored foam model.

A method for monitoring foam within a vessel, the method comprising:

• detecting movement of a sensor device within the vessel via an accelerometer;
• generating movement data based on the detected movement;
• and
• determining a foam status of the vessel based on the movement data, wherein:
• the sensor device is enclosed in a water-tight housing that floats on liquid contained within the vessel;
• the accelerometer tracks multi-axis movement of the sensor device;
• and
• the foam status is updated in real time based on how foam formation alters the movement data relative to a baseline motion profile in the absence of foam.
