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

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.

Frequently Asked Questions: Compressed Air Surveys

How does portable ultrasound work?


Portable ultrasound detects high frequency vibration of sound waves to discern relevant and irrelevant sounds above the human hearing threshold, specifically frequencies of 20 kHz and up. The amplitude of the sound wave is a measure of intensity of acoustic energy and is displayed in decibels. We use algorithms developed by NASA to calculate leak waste for all compressed gasses. PM TECH’s trained technicians are certified by ASNT to conduct ultrasound inspections and use only the highest quality equipment.




Why does my business need compressed air leak detection?


Compressed air or gas leaks can be a significant source of wasted energy in industrial environments. In addition, compressed leaks contribute to operating losses which has a negative effect on operations. Frequently purchasing unnecessary, additional compressed air and cycling equipment to maintain system pressure drives costs up, shortens equipment life, and adversely affects productivity. The impact to efficiency results in increased run times, which are an additional source of frequent repairs.




How much do compressed air or gas leaks cost my facility?


A leak survey can identify costs due to compressed air or gas leaks, and more. A proper survey includes calculating system data, including PSI, CFM, HP, Runtime, and dB levels. All leaks are located and identified then PM TECH calculates and computes the cost of the leak, the potential savings on gases and electrical power, and carbon footprint improvement, providing a more efficient operation and even utility rebates.
