the two flow rate measurements as separate parameters over the NMEA 
2000 network. 

 

3.4  Configuring Channel #0 

3.4.1  Enabling/Disabling Channel #0 

By default, the channel is enabled and will measure the flow rate and transmit it over the 
NMEA 2000 network. If this parameter is programmed to “Disable”, the channel will be 
completely disabled and will not measure flow rate nor transmit it over the NMEA 2000 
network. 
 

3.4.2  Configuring Channel #0 Engine Instance 

Program this parameter to match the desired engine instance number of the flow rate and total 
fuel used for this channel. You can program this parameter to any value between 0 and 252. 
 

3.4.3  Configuring Channel #0 Engine Label 

Program this parameter with a text string which identifies the particular parameter being 
monitored by this channel.  Maretron display products will display this label text when you are 
selecting data to display. 

3.4.4  Configuring Channel #0 K-factor 

Program this parameter to match the K-factor that appears on the flow sensor connected to 
this channel. 
 

3.4.5  Configuring Channel #0 Data Damping Period 

You can configure a damping parameter to smooth the flow rate readings or make them more 
responsive. The data damping is configurable between 0.2-25.0 seconds. The default data 
damping period is 3.0 seconds. 
 

3.4.6  Resetting the Total Volume Recorded for Channel #0 

The FFM100 maintains the total volume recorded in EEPROM, so that it is maintained across 
power cycles. Select this menu entry to reset the total volume recorded to zero. 
 

3.4.7  Configuring Channel #0 Temperature Instance 

Program this parameter to match the desired instance number of the temperature reading for 
this channel. You can program this parameter to any value between 0 and 252. The default 
value for this parameter is 0. 
 

3.4.8  Configuring Channel #0 Temperature Source 

Program this parameter to match the desired instance number of the temperature reading for 
this channel. You can program this parameter to any value between 0 and 252. The default 
value for this parameter is 129 (User Defined).
