3.4.9 Configuring Channel #0 Temperature Label
Program this parameter with a text string which identifies the particular temperature parameter
being monitored by this channel. Maretron display products will display this label text when
you are selecting data to display.
3.5 Configuring Channel #1
3.5.1 Enabling/Disabling Channel #1
NOTE: This parameter is available only when the Operating Mode of the FFM100 is set to
“Two Independent Flow Rates”.
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.
3.5.2 Configuring Channel #1 Engine Instance
NOTE: This parameter is available only when the Operating Mode of the FFM100 is set to
“Two Independent Flow Rates”.
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.
3.5.3 Configuring Channel #1 Engine Label
NOTE: This parameter is available only when the Operating Mode of the FFM100 is set to
“Two Independent Flow Rates”.
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.
3.5.4 Configuring Channel #1 K-factor
Program this parameter to match the K-factor that appears on the flow sensor connected to
this channel.
3.5.5 Configuring Channel #1 Temperature Coefficient
NOTE: This parameter is available only when the Operating Mode of the FFM100 is set to
“Differential Mode”.
In a diesel engine, the diesel fuel is used to help cool the fuel injection system. Therefore, the
fuel returned from the engine to the tank has a higher temperature than the fuel sent to the
engine from the tank. Diesel fuel expands when heated. To calculate the most accurate fuel
usage measurement, the FFM100 accounts for this expansion by sensing the temperature at
the supply flow sensor and the receive flow sensor, and calculating the effect of the
temperature difference on the fuel expansion. In order to do this compensation, this parameter
