Miniflo-L Operating Manual Miniflo-L Although not required by the FAA, it is recommended that this manual be attached to the FAA-approved Flight Manual, or always kept on board for reference. 1. GENERAL DESCRIPTION Miniflo-L™ is a Digital Fuel Management System designed to provide complete fuel management information under real flight conditions without any manual entry of data (after entry of the initial fuel on board information).
Miniflo-L Operating Manual THE SYSTEM PROVIDES 1.1.1 SPECIFIC RANGE Specific Range (NM/GAL) = Ground Speed (Kt.)/Fuel Flow per hour. This is an indication of how efficient the cruise is and the optimum cruise speed can be determined by selecting the power setting, which yields the highest nautical miles per gallon.
Miniflo-L Operating Manual 1.1.5 FUEL FLOW The system provides a digital readout of the fuel per hour to a tenth of a gallon up to 100 gallons and to the nearest gallon above 100 gallons. For the pounds version, the readout is to the nearest pound up to 999 lbs./hour and to the nearest 10 lbs.
Miniflo-L Operating Manual SYSTEM COMPONENTS The system consists of three (3) basic units: the fuel flow transducer, the navigation receiver (Loran-C or GPS) and the panel mounted unit. 1.2.1 FUEL FLOW TRANSDUCER The fuel flow transducer mounted in the fuel line measures the flow of fuel and generates electrical pulses directly proportional to the fuel flow.
Miniflo-L Operating Manual TEST FUNCTION Diagnostic software is built into the system. To activate it, press the ENTER/TEST button. All of the digits will be sequentially on in a rotating pattern for ten seconds. If the test is successful, the word “Good”...
Miniflo-L Operating Manual PREFLIGHT PROCEDURES Miniflo-L™ is a fuel flow measuring system and NOT a quantity- sensing device. A visual inspection and positive determination of the usable fuel in the fuel tanks is a necessity. Therefore, it is imperative that the determined available usable fuel be manually entered into the system.
Miniflo-L Operating Manual Move the REM/USED toggle switch to the REM position to increment the full fuel number or to the USED position to decrement the number. (The longer you hold the switch in position, the faster the number will be updated.) After reaching the correct total usable fuel figure, press the ENTER/TEST button and the computer will store that number as full fuel.
Miniflo-L Operating Manual Lt ( ): Loran or GPS type appears in the left window (without signal, will display “LOF”). The distance to waypoint or destination is displayed as shown on the Loran-C or GPS receiver to check the Data Interface Integrity (not available without signal).
Miniflo-L Operating Manual FUEL TANKS FULL There are two methods to enter full fuel: the ramping method and the FULL/ADD toggle switch method. Ramping Method • Move the REM/USED toggle switch to the REM position and hold. • Press the ENTER/TEST button to increment the fuel remaining until the total usable fuel is reached.
Miniflo-L Operating Manual PARTIAL FUEL ADDED There are two methods to enter partial fuel: Ramping Method Add the amount of fuel from the refueling meter to the amount of fuel remaining. Enter the total using the following steps: • Move REM/USED toggle switch to REM position and hold. •...
Miniflo-L Operating Manual CORRECTING FUEL ON BOARD ENTRY ERROR In case an error has been made by exceeding the correct amount in entering the total usable fuel, move the REM/USED toggle switch to the USED position and simultaneously press and hold ENTER/TEST button.
Miniflo-L Operating Manual 3.1.2 FUEL USED Fuel used is displayed by moving the REM/USED toggle switch to the USED position. The information is shown on the right display window as long as the switch is held in the USED position and for three seconds after the switch is released.
Miniflo-L Operating Manual 3.1.7 FUEL RESERVE Fuel reserve is selected by rotating the rotary switch to the FUEL RESERVE position. The information is shown on the right display window and represents the fuel that will be available when the aircraft reaches its destination as indicated on either the selected waypoint or the final destination (if the total distance record is provided in the serial message.) This assumes the aircraft ground speed,...
Miniflo-L Operating Manual 3.2.3 LOW ENDURANCE The Miniflo-L™ can be configured to display a warning based on the time remaining to fly. When the rotary switch is in the ENDURANCE position, and the actual endurance is less than the pre-programmed Endurance Warning Time, the data in the right half of the display flashes.
Miniflo-L Operating Manual 5. ERROR MESSAGES ERROR 1: Due to the necessity of Group 1 settings, if the Flow Meter is set to Operate Mode and the checksum of Group 1 is bad, the display will flash: E1. This refers to Error 1, Group 1. The flow meter will not continue to function after this point, and will continue flashing E1, alerting that the flow meter must be serviced.
Miniflo-L Operating Manual 6. CONFIGURATION DATA ENTRY Manual Entry Mode Ordinarily, the fuel flow indicator has been set up by the factory to match the K-factor of the supplied transducers and other set-up information. However, there are built-in provisions to change the set-up.
Page 22
Miniflo-L Operating Manual Manual Entry Mode can be accessed in two ways: one providing access to both Group 1 and Group 2 values, and one providing access to only Group 2 values. The access to Group 2 values can be obtained while the unit is installed in the aircraft.

Miniflo-L Operating Manual Operation Mode vs. Entry Mode If Switch 1 is set to F and Switch 2 is set to E, the unit is in Entry Mode. This is the only mode that will allow the setting of Group 1 values onto the non-volatile memory of the unit.
Page 24
Miniflo-L Operating Manual Manual Entry Mode There are two ways to access the Manual Entry Page. Set Switches 1 and 2 to Entry Mode and power up. This allows access to both groups. If the Switches are not set to Entry Mode, while running under normal conditions, press the ENTER/TEST button to start the test mode.
Page 25
Miniflo-L Operating Manual The values displayed can be adjusted with the FULL/ADD toggle switch. ADD increments the value, and FULL decrements the value. As you hold ADD or FULL, the scrolling rate will increase up to a maximum speed. If you wish to jump directly into the fastest scrolling speed, while holding the FULL/ADD toggle switch, press the fuel USED or fuel REM button.
