Compressed Air / Gas Inspections


Portable Ultrasound Technology

PM Tech utilizes portable ultrasound technology to detect compressed air and gas leaks and prevent critical failures. This service will improve efficiency, save energy, and extend equipment life.

Compressed Air/Gas Leak Survey

PM Tech uses portable ultrasound technology to locate and quantify pressurized leaks in systems. We calculate waste based on leak size, utility cost, operating cost, and compressor/s efficiency. We tag, photograph, report, and quantify the leak type, waste quantity, and the cost of each leak.  Documented savings from our surveys are used to generate utility incentives, rebates, and to improve the carbon footprint.

How Compressed Air Surveys Work

Portable ultrasound uses high frequency vibration of sound waves to measure relevant and irrelevant ultrasounds above the human threshold. A measurement level of amplitude of intensity is displayed in decibels and compared to a baseline to detect leak size. We use data developed by NASA for all compressed gases to calculate waste.

Structure-borne ultrasound detectors will:


  • Locate Anomalies

  • Prevent Failures

  • Improve Operations

Airborne Ultrasound vs Structure Borne Ultrasound

PM Tech uses ultrasound inspections both in conjunction with infrared and vibration analysis and independently with contact or non-contact applications. Structure-borne, or contact ultrasound, on rotating equipment can locate developing problems and potential failures by listening to the equipment while in operation. Airborne, or non-contact ultrasound, is used in compressed air/gas leak inspections to pinpoint a leak location. Non-contact ultrasound is also used in electrical inspections to identify corona, arcing, and tracking conditions.
