A label may be assigned to the FFM100 as an aid to identifying the device over the network. Typically
this label will describe the location of the FFM100.
6.12.3 Operating Mode
The FFM100 can operate in one of two user-selectable operating modes:
Differential – this mode is used for diesel engines that recirculate unused fuel back into the fuel take.
These engines will have separate supply and return fuel lines.
Two Independent Sensors – the FFM100 can measure flow rates from two independent sources; for
example, a water flow rate on one channel and a gasoline fuel flow rate on another channel.
6.12.4 Channel #0…
This submenu contains configuration parameters for Channel #0. This menu looks different
depending on whether the FFM100’s operating mode has been set to “Differential” or “Two
Independent Sensors”.
