What is Ultrasound?H igh frequency sounds that are above the range of humanhearing

The starting point is at 20 k Hz and up

There are three ( 3 ) Generic Divisions of Ultrasound

Energy Facts

Optimi z ation of compressed air systems can provideenergy efficiency improvements of 20 50%.

Many industries use compressed air as power sources for

tools and equipment used for pressurizing, atomi

zing,agitating and mixing applications.

Compressors using variable speed drives are savingenergy, while simple measures like detecting and fixingair leaks remain all-important

More Energy Facts

A U.S. Department of Energy study notes that poorlydesigned and operated air systems in American factorieswaste from $1 Billion to as much as $3.2 Billion annually.

The U.S. Department of Energy estimates that upwards of30% of all compressed air produced in the USA is lostthrough Artificial Demand ( LEAKS )

Compressed Air Leak Detection

Air is NOT FREE !!!!!!

According to the U.S. Department of Energy, compressedair is the most costly utility in plants today

It takes a lot of energy to produce Compressed AirCompressed Air leaks cost MONEY!!

Things to Consider

1. Optimi z e Sensitivity

(Do not over adjust)

2. Move AroundWatch for tripping ha z ards

Watch for bumping ha z ards (head, back, knees, elbows)

3. Follow Loudest Sound

4. Shield5. Confirm

Conclusion

Air is not Free! Compressed air is the most costly utilityin plants today

Ultrasound instruments are ideally suited to locate

compressed air leaksPlan your survey carefully

Tag & Report all leaks

Follow up on all repairs

Report your Savings !!!
