An ultrasonic leak detector finds compressed air leaks by responding to

  • A.the temperature drop at the point of the leak
  • B.the pressure fluctuation in the main
  • C.the moisture the escaping air carries with it
  • D.the high frequency noise the escaping jet makes

Answer: D

Turbulence at a small orifice radiates strongly above the audible range, where the factory's own noise does not reach, so a leak is located in a running plant. Compressed air leakage of twenty or thirty per cent of generation is not unusual and is among the largest single opportunities in many audits.
