Perhaps the most comprehensive and easy to use fuel flow, fuel  range, fuel endurance and fuel level computer available. Includes fuel low  alarm and can use our dual range, low cost fuel flow sender as well as  other senders. Can interface to an optional fuel level sender with full multi point calibration.

Please note: We do not recommend usage of fuel flow based fuel level monitoring as primary fuel level display. Calculation of level from flow is a relative operation and subject to errors. This may only be used as secondary fuel level display for purpose of range and endurance calculations if a primary, direct indicating level display is available. This condition is met if you fit the optional fuel level sender.

Building on the succesful concept of the FF-1, the FF-2  provides for a multitude of different operating  requirements with 13  destinct modes. The FF-2 can interface to two fuel flow senders and two  fuel tank level senders at the same time.
Supported modes include  single or dual fuel flows, differential fuel flow, single or dual tanks  either using calculated levels or measured levels using multi point  calibrated level senders. Fuel usage accumulators are also provides plus  all the functions of the FF-1.

Please note: We do not recommend usage of fuel flow based fuel level monitoring as primary fuel level display. Calculation of level from flow is a relative operation and subject to errors. This may only be used as secondary fuel level display for purpose of range and endurance calculations if a primary, direct indicating level display is available.

This is a general purpose indicator mainly used for adding additional displays to the AHRS-2 packages.
