  4. What firmware changes have taken place on the Maretron FPM100? (2018-4-27) In tank mode, re-enable operation range checking at 4mA (20mA report 100%). maximum operating range while operating in pressure mode to 1mA - 24mA (3681). FPM100 will report actual pressure between 4mA – ... Read More
  5. I see that the FPM100 has an accessory for measuring pressures in the range of -1Bar to 1 Bar. Can I use this sensor to monitor my fuel filters? Yes, the FPM100 can transmit vacuum pressure data on the NMEA2000 bus by using Maretron sensor part number PT-V-0-1BAR-01. This sensor must be installed on the vacuum side of your fuel filter to help you determine fuel filter health displayed on a Ma...
