What firmware changes have taken place on the Maretron FFM100 Fluid Flow Monitor?

You can update your device using the N2KAnalyzer software tool.

  • Corrected a problem where the device needed to be reset after having its configuration changed from 3-phase sensor to 1-phase sensor (4224)
  • Added support for differential mode with single-phase fuel flow sensors (e.g., Coriolis sensors) (4169)
  • Updated NMEA 2000 database version to 2.100 (4226) (2014-10-31)

  • Corrected problems in total volume recording¬† (2014-04-16)

  • Reduced fluctuations in flow readings at low flow rates.
  • Changed default fuel flow damping period to 5 seconds.
  • Save cumulative fluid volume with higher resolution and more often.
  • Improved the resolution of the K-factors you can type in when you are configuring the FFM100 so you can use the full resolution printed on the fuel flow sensor labels (requires DSM150/DSM250 F/W or later). (2013-07-09) 

  • Added support for the 130316 Temperature Range, Extended parameter group
  • Corrected a problem where reset of the Trip Volume parameter didn't work in some cases
  • Corrected a problem where the FFM100 transmitted incorrect temperature values if the thermistors in the flow sensors were incorrectly connected. It will now transmit "Data Not Available" in this case
  • Updated the supported NMEA 2000 database version to 2.000 (2012-08-15)

  • Corrected NMEA 2000 protocol issue where each channel had used its own fast-packet Sequence ID.
  • Both channels now share a common sequence ID, per the NMEA 2000 specification

  • Added support for single-phase sensors (typically used for non-fuel fluid flow applications)
  • Added support for Maretron proprietary fluid flow rate and fluid volume PGN's, for non-fuel flow applications

Version 1.0.1

  • Initial Release
