The prerequisite for using this guide requires the use of a Windows PC and Maretron's N2KAnalyzer program installed. The hardware required for Maretron device configuration is the USB100 or IPG100 Gateway connected to a powered N2K network with a FFM100 installed. Please note the DSM150/250/410 can provide the same configuration options as well, but only if the display is running firmware version 1.5.22 or higher.
** Please note **
If you have a single gas engine setup but also have a return fuel line please refer to the article listed below referencing a single diesel setup, this will require an additional Fuel Flow Sensor module to accurately calculate fuel consumption.
Identify the K-factor value for the sensor to be installed. K-factors are located on the sensors label as shown.
* Each sensor may be different, therefore identify appropriately for each engine.
** Please be attentive to direction of flow stamped on product for proper installation
** Proper installation of fuel flow sensors should include a bypass setup for safety as pictured below
Connect your wiring to the appropriate channels as presented below (Single Setup 1-6)
Connect your Maretron gateway (USB100 or IPG100) to the NMEA2000 network
Open Maretron N2KAnalyzer and identify the Maretron FFM100 unit by its Serial Number
Identify the Maretron FFM100, right-click and select Configure Device
Under the General tab, match your details to sample image below
- Operating Mode: Two Independent Sensors
- Sensor for Channel # 0: 3-phase, Channel # 1: Disable
- Your K-Factor value appropriately for the installed sensor
- Fluid Type: Fuel (Gasoline)
- Instances for Channel # 0 are all 0, label appropriately
- Temperature Source for Channel # 0: User Defined 129
Select option Put Config To Device
You will receive a confirmation for applying the new configuration details, select OK
After completing your configurations of both the Port and Stbd Engines on the FFM100 module, with the engines running, you will now see real time data in the Flow Rate fields.
Now that setup is complete examine data available from the FFM100 peration.
- Flow rate should be a positive number.
- If you notice a negative flow rate: examine installation, specifically the orientation of fluid flow arrow located on the sensor lid.
Symptoms of erroneous fluid flow readings such as negative flow rates, more fuel returning to tank than sourced.
Erratic fluid flow rate values:
Most common issues can range from the following application faults:
- Inadequate filtration causing poor sensor performance
- Sensor damage due to debris clogging or damaging sensor internals.
- Fluid pass through (no readings from sensor engine running)
- Sensor wiring issues
- Sensor installation reversed (wiring or physical)
