Assignee: KPR U.S., LLC
Field: Medical technology (Instruments)
Classification: CPC A | IPC A

Claim 8:
9. A method of operating a flow control apparatus, the method comprising:
emitting via a first sensor component a first ultrasonic signal in a first direction through a portion of a pump set;
emitting via a second sensor component a second ultrasonic signal in a second direction through the portion of a pump set, the second direction being opposite the first direction;
detecting the first ultrasonic signal to determine a first sensor reading;
detecting the second ultrasonic signal to determine a second sensor reading;
comparing an amplitude of the first sensor reading to an amplitude of the second sensor reading;
detecting a condition of the pump set based on the comparing of the first sensor reading and the second sensor reading;
detecting the condition of the pump set by the flow control apparatus based on a greater reading of the amplitude of the first sensor reading and the amplitude of the second sensor reading; and
operating only the first sensor component or the second sensor component based on the greater reading of the amplitude.
