Claim 14:
15. A flow control apparatus comprising:
a memory; and
at least one processor coupled with the memory and configured to:
emit a first ultrasonic signal in a first direction through a portion of a pump set;
emit a second ultrasonic signal in a second direction through the portion of the pump set, the second direction being opposite the first direction;
detect the first ultrasonic signal to determine a first sensor reading;
detect the second ultrasonic signal to determine a second sensor reading;
compare an amplitude of the first sensor reading to an amplitude of the second sensor reading;
detect a condition of the pump set based on the comparing of the first sensor reading and the second sensor reading;
detect the condition of the pump set based on a greater reading of the amplitude of the first sensor reading and the amplitude of the second sensor reading; and
operate only the first ultrasonic signal in the first direction or the second ultrasonic signal in the second direction based on the greater reading of the amplitude.
