Summary:         

  • Fast operation - only one switch with LCD text status display. 
  • The ELF receiver channel is fully tunable in frequency range 10Hz to 30Hz with digital tuning, crystal accuracy and stability. Ensures the AGM is "On Frequency" at all times.
  • Improved signal to noise ratio means better ability to detect pigs in deeper pipelines, and fewer false passes.
  • Selectable ELF receiver Bandwidth handles Pulsing and Continuous transmitters.
  • Automatic Magnetic or 22Hz (ELF Receiver) pig pass logging with ability to prioritize magnetic or 22Hz (ELF) pass logging.
  • Detect different (batch) pigs in the same pipeline and know which pig just passed. 
  • Wireless link for control and data file download (no cables required).
  • Easy to use:  No computer required for field operation.  
  • Change settings using a Computer Program.
  • Setup and control by wireless computer link using Windows XP®(SP2) and a USB wireless adapter such as the Model KC-USB
  • Accuracy assured with Automatic Synchronization to GPS clock. 
  • Pig Passage data are saved to the onboard 1 giga-byte memory card with ample space to save thousands of passes -- ideal for multiple runs.
  • Pass data files are organized into folders so data from separate runs can be saved in different folders.  Files are saved in Windows® compatible format.
  • Very long battery life. Expect 150 days on two alkaline D cells.
  • Waterproof (IP65 or better).  Good for multiple runs.   
  • DM3 with Display operating temperature range -8°F to 158°F (-22°C to +70°C).
  • DM3 may be converted for temperature range -40°F to 185°F (-40°C to +85°C) with the optional Extreme Temperature Kit.  At temperatures below -4°F (-20°C), Lithium cells are needed. 
  • Notification that Pig passed with or without a computer.
  • Local Pig Passage Event notification  i.e. AGM to Truck, range up to 30+ feet, requires laptop or Remote Display AlarmSmartphone® cell phone program for remote monitoring also available. 
  • Optional external sensor.
  • Small easy to carry.  6 1/4" x 3 1/8" x 3 3/8"  (16cm x 8cm x 8.6cm).
