Detection system for flow control apparatus

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 though a portion of a pump set;
• emitting via a second sensor component a second ultrasonic signal in a second direction though 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;
• and
• detecting a condition of the pump set based on the comparing of the first sensor reading and the second sensor reading.

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 though a portion of a pump set;
• emit a second ultrasonic signal in a second direction though the portion of a 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;
• and
• detect a condition of the pump set based on the comparing of the first sensor reading and the second sensor reading.
