Air Leaks
- A Calculated Cost at the Engineering Society of Detroit
Conference |
Allan Rienstra, Editor
The Ultrawave Technology Report
 |
I had the good fortune of attending an energy conference
hosted by DTE Energy this month in Novi, MI and found it to
be a real eye opener. The luncheon keynote delivered by Mr.
J. Peter Lark, Chairman of Michigan's Public Service
Commission revealed the state's 21st Century Energy Plan
submitted to Governor Jennifer Granholm. The plan addresses
Michigan's commitment to renewable resources, energy
efficiency measures, and the cleanest available
utility-built generation. As a non-resident of the state I
found his speech motivating. It left me wondering about the
status of other states and provinces and their collective
initiatives to cleaner power and energy conservation.
As many know my favorite energy efficiency topic is
compressed air leak management. During the conference I
found myself engaged in many conversations with various
groups from DTE Energy, University of Michigan, and the big
automotive groups about their compressed air leak
initiatives. Several times I was asked about justification
and cost calculation for air leaks. "How can we reasonably
estimate the potential or realized cost savings?". Luckily
for me I came armed with the SDT Air Leak Cost Calculator on
CD-ROM. I was able to distribute 50 of those CD's at the
conference and when my personal stock was depleted I
directed others to our website where its available as a
free download.
With more than 1000 attendees and 100 exhibits I've decided
to put this conference on my schedule for 2008. I'll be
curious to follow up with some of my newly made
acquaintances to see just how far they advanced their energy
savings initiatives.

Equipment
Tip - Tuning Frequency Filters Interference |
|
Ultrasound detectors work best in environments with
high levels of audible background noise by filtering
away sounds that make it impossible to find leaks
with the unaided ear. But other sources of
ultrasonic noise can interfere with high frequency
inspections.
Some
examples of interference are electronic noise from
older PC monitors, modems, printers, and VFD's. Arc
welders generate high levels of ultrasound too.
Parasite ultrasonic noises are random but often have
distinct frequencies, while compressed air leaks are
broadband sounds with peaks occurring throughout the
spectrum. Tune out ambient noises by shifting the
detector’s frequency away from the competing
ultrasonic interference making detection in ANY
environment a success.
On your
SDT170 press the menu key and toggle to "settings".
Press enter and then toggle to "sensor options".
Press enter key and then toggle to "discover
frequency". Press enter key and the SDT170 returns
to the main measurement screen and displays 38.4 kHz
(the center frequency). Use the two "M" keys on the
keypad to shift the frequency up or down while
listening in the headphones. Stop when the competing
frequencies are gone, but air leaks are still
detectable.

New i-presentation
explains step by step how to use the leak cost calculator |

An iPresentation Tutorial by
Allan Rienstra SDT North America
According to The Compressed Air Challenge, a voluntary
collaboration charged with improving the performance of
compressed air systems, the cost of a single quarter inch
leak can waste $ 8,000.00 of energy per year; higher in
states where the cost per kilo watt hour exceeds five cents.
The Department of Energy says that compressed air accounts
for 1.5 billion dollars per year in energy costs in the US
and 0.5 percent of emissions. But how can you determine what
compressed air leaks are costing at your facility?
The cost calculator from SDT is a powerful resource. View
this presentation online to learn how to use the calculator
to justify an air leak management program at your facility.

Leak detection in a Balloon
Factory!!
(Who wants to buy a leaky balloon anyway?) |
|
NEW!!!
Interactive Leak Calculator Estimates the Cost of Found
Leaks |
 |
Now calculating the benefits of your ultrasonic leak survey
program is easier, and more accurate than ever. Our simple
to follow program asks you to enter standard information
about your compressed air system and compressor equipment.
Then, choose between two options for calculation
1. Estimated Orifice Size
2. dBµV measured with SDT 170 Meter
Green boxes indicate data entry requirements by you and
Calculations are automatically provided in the Red boxes.
