Gas Technology Institute Project

• Began in late 90’s • Funding through

GRI/GTI, OTD, PHMSA • Research supported by

many utilities • Technology licensed to

Sensit Technologies and commercialization efforts began in mid 2011

History

June 25, 2012 5

• Locate unmarked piping systems – Gas distribution lines – Sewer laterals – Field tile systems

• No access to the utility system needed

• One button operation • Easy to interpret data • Detects multiple pipes • Locates within regulatory

requirements • Operate in soil, grass, concrete and

asphalt ground covering

Ultra-Trac APL – Acoustic Pipe Locator Commercial Goal

Transmit-Receive Set

Obstacle (pipe)

ground surface

R T

reflected wave

Transmitter sends “pings” Receiver listens to reflected ping. Strength and duration of pings are

converted to useful info on display

Each test of the transmitter and receiver device is a “slice”

A group of “slices” is a “scan”

How does it work?

Ultra-Trac APL – Acoustic Pipe Locator How to Use

•Start up (less than 1 minute) •Lay down a measuring tape for reference •Select a Scan direction (L->R or R->L) •Select 6 or 12” slices •Place unit on ground and wait for check marks on display indicating receivers are ready •Place foot on unit •Push handle forward (this creates the coupling to the ground) •Push the trigger button •Unit will tell you go to the next slice in seconds. •Must do at least 4 slices for a scan •Press “calculate” to display results.

June 25, 2012 9

• Review display for location of detected substructure and mark

• Instrument will detect up to 3 objects per scan

• The results are matched to measuring device to the nearest 6 or 12 inches depending on scan width selectect

• Repeat procedure 10-20’ away to create a point to point identification of substructure

Ultra-Trac APL – Basic Use

June 25, 2012 10

• Development work continues – Fine tuning items found during

alpha evaluation – Ruggedizing housing – Customizing receivers for more

abusive environment • Successful field demo in May

w/OTD members • Parts ordered for prototypes • Field implementation of prototypes

in July/Aug • Beta evaluation with OTD members • Expected product launch in 3Q12
