The All -In-One L22M fills a need for pig locating, tracking, and AGM Recording. Actively track your ILI tool in Real Time, while automatically recording all data to your laptop's hard drive. As the L22M uses GPS timing, the saved data can be played back after the inspection run and precision AGM data can easily be extracted with a minimum of effort.
Use the L22M to confirm the ILI tool's 22Hz transmitter is working, and should it happen that the pig gets stuck, the L22M can be used without a computer to search for the pig.
To assist in the search process, the L22M has a sharp high contrast display and uses a wireless headphone or ear piece (as used with cell phones) to give audio alerts when a signal has been located. NO computer is needed when searching for a stationary (stuck) pig.
The L22M has the very latest electronics and the receiver is designed to minimize false alerts, better than any other receiver on the market. The uncluttered headphone connection allows the user the freedom to concentrate on walking safely on the pipeline right of way, avoiding snakes, pot holes, and other obstacles.
The other unique feature of the L22M is it can also be used to
search for a stationary Magnetic (MFL) tool, and last I checked this
is the only search receiver that has this ability.
Real Time Pig Tracking.
Sit in the comfort of your truck with
the L22M outside on the pipeline right of way.
Watch the pig pass in Real Time and automatically record the data
to your laptop. Wireless connection uses Bluetooth ® and
depending upon the nature of the terrain can connect up to 300 feet
from the truck.
New Feature! AGM Recording.
Select
AGM Recording
The
display is updated with Type of Event and UTC time of the event.
The L22M records both Magnetic and 22Hz (ELF) to on board memory for up to 570 hours in multiple (1000's) recordings. The Recorded data is referenced to UTC (GPS) time so any point of interest in the data can be used as a true AGM time reference point.
While recording the L22M reports ELF or Magnetic events to the LCD Graphics display. After a pig passage these events can be viewed on site without a computer to confirm the data has been recorded, and can be downloaded to a PC at a later time.

the event on site without a computer.
ELF Pig Passage Time Scale is accurate UTC (GPS) time. The well defined NULL tells us when the pig's transmitter was under the L22M AGM. IN this case the pig passed at 16:52:30 . A more precise time can be viewed by connecting to the L22M and viewing the data. The exact passage time is 16:52:30.95 2011/December/16.
The playback program shows a list of recording with Start and Stop Times. When a Recording is selected the Event List is populate and then it's just a matter of clicking the event to see the passage. This software is included in the price.

Sharp Transreflective Graphics Display.

The above image of a 22Hz signal is very sharp even in midday blue sky Texas sun. This display loves the sun and does NOT turn black as is the case older displays. The Transreflective technology means this display uses light from both directions, existing light for daytime viewing or backlight for night viewing.

Backlight for night time tracking. This image shows the NULL of a 22Hz transmitter.

Sharp high contrast "Transreflective" LCD display in direct
sunlight. It will not turn black as is the problem with other LCD
displays. This photo after 3 hours in blue sky noon day Texas sun.

22Hz Transmitter (slow moving pig)
Portable: Size (L-W-H) 9.25" (24cm) - 3.25" (8.5cm) - 3.25" (8.5cm)
Weighs just 2.9 lbs. (1.32 kg) with batteries.
A truly portable search receiver that gives the user the freedom to move around.
No longer do you have to lug 14 lbs. of wired clutter along the pipeline right of way, like some old technology receivers that use 27" antenna weighing 6 1/2lbs, with a 7 1/2lb receiver, cables and headphones.
This unit is small and light (<3lbs) and will do much more than receivers costing almost twice the price.
