Pump control based on bubble detection

A method of operating a pump system, comprising:

• identifying a configuration of a pump system including characteristics of a tubing;
• operating the pump system according to the configuration to pump liquid to a destination via the tubing;
• receiving a signal from a bubble sensor indicating presence of a gas bubble within the tubing;
• determining a quantity of bubbles detected based on the signal;
• determining an alert in response to the quantity of bubbles detected exceeding a threshold;
• and
• stopping the pump system after a safe operating time from the alert, wherein the threshold and the safe operating time are based, at least in part, on the characteristics of the tubing.

A pump controller, comprising:

• a memory storing computer executable instructions;
• and
• a processor communicatively coupled to the memory and configured to execute the instructions to:
• identify a configuration of a pump system including characteristics of a tubing;
• operate the pump system according to the configuration to pump liquid to a destination via the tubing;
• receive a signal from a bubble sensor indicating presence of a gas bubble within the tubing;
• determine a quantity of bubbles detected based on the signal;
• determine an alert in response to the quantity of bubbles detected exceeding a threshold;
• and
• stop the pump system after a safe operating time from the alert, wherein the threshold and the safe operating time are based, at least in part, on the characteristics of the tubing.
