Bubble detection

A processing system for use with a sensor system comprising a plurality of sensors arranged along a fluid channel, the processing system comprising one or more processors configured to:

• receive readings from each sensor of the plurality of sensors, wherein each sensor is configured to detect a different chemical characteristic of a fluid present in the fluid channel;
• identify an anomaly in the readings received from at least one of the plurality of sensors based on comparing the readings from the at least one of the plurality of sensors to forecasted values based on a time-series predictor specific to the chemical characteristic for the at least one of the plurality of sensors;
• determine that readings from a first sensor of the plurality of sensors comprise first anomalous readings with a first time associated with the first anomalous readings;
• determine that readings from a second sensor of the plurality of sensors comprise second anomalous readings with a second time associated with the first anomalous readings;
• determine, based on data associated with the first and second anomalous readings and location data associated with the first and second sensors, whether one or more bubbles are present in the fluid channel of the sensor system, wherein the location data associated with the first and second sensors comprise relative locations of the first sensors and the second sensors along the fluid channel;
• determine, based on the first time being substantially same as the second time and the first sensor being adjacent to the second sensor, that a bubble is adjacent to the first sensors and the second sensors;
• and
• transmit a control signal to a pump to cause fluid to be flushed through the fluid channel in response to determining that one or more bubbles are present in the fluid channel.
