3 Microflo-L ™ Although not required by the FAA, it is recommended that this manual be attached to th e FAA-a pproved Flight Manual, or always kept on board for reference.
4 1.1 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.
5 1.1.5 FUEL FLOW The system provides a digital re adout 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.
6 1.2 SYSTEM COMPONENTS The system consists of three (3) basic units: the fuel flow transducer, the navigatio n 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 genera tes electrical pulses directly proportional to the fuel flow.
7 1.3 TEST FUNCTION Diagnostic software is built into the system. To activate it, press the ENTER/TEST button until all of the display digits fill with a checkerboard pattern, and then release it.
8 2. PREFLIGHT PROCEDURES MICROFLO-L is a fuel flow measuring system and NOT a quantity-sensing device. A visual inspec tion and positive determination of the usable f uel in the fuel tanks is a ne cessity. Therefore, it is imperative tha t the determ ined available usable fu el be manually entered into the system .
9 6. After reaching the correct total usable fuel figure, press the ENTER/TEST button and the comput er will store that number as full fuel. The word “ FUL” disappears and the com puter will return to the opera ting mode. Release the ADD/FULL toggle switch.
10 Move the USED/REM toggle swit ch to the REM position. The system will display the fuel rem a ining on board. The pilot should confirm this figure with the actual fuel on board. 2.3 NO FUEL ADDED This automatically stores inform ation concerning previous fu el levels, even in the case of a pow er down.
11 2.5 PARTIAL FUEL ADDED There are two methods to enter partial fuel: Ramping Method Add the amount of fuel from the refueling m eter to the amount of fuel remaining. Enter the total using the following steps: 1. Move USED/REM toggle switch to REM position and hold.
12 switch in the USED position and u se the ENTER/TEST button to control the decrem enting. Note: Adding or subtracting fuel by any method resets the fuel used value to zero. 3. INFLIGHT OPERATIONS 3.1 INSTRUMENT OPERATION 3.1.1 FUEL FLOW For Single Engine Aircraft: FUEL FLOW is displayed continuously on the left display window.
13 3.1.5 NAUTICAL MILES PER GALLON Nautical miles per gallo n is selected by rotating the rotary switch to the NM/GAL position. The inf ormation is shown on the right display window. 3.1.6 FUEL TO DESTINATION Fuel to destination is selected by rotating the ro tary switch to the FUEL TO DEST.
14 3.2 WARNINGS 3.2.1 NOT ENOUGH FUEL When the rotary switch is in FUEL TO DEST. position, the information in the display window flashes if fuel on board is insufficient to reach either th e destination se lected as the active waypoint or the final dest ination (if that total distance record is provided in the seri al message).
15 3.3 BRIGHTNESS CONTROL The display brightness is cont rolled by the BRIGHT/DIM toggle switch. Moving the BRIGHT/DIM toggle switch to BRIGHT repeatedly will make the disp lay brighter; moving it to DIM repeatedly will dim the display. Th e default brightness after power up is full brightness.
16 5. ERROR MESSAGES ERROR 1: Dues to the necessity of Group 1 settings, if the F low Meter is set to Operate Mode and the checksum of Group 1 is b ad, the display will flash: E1 .
17 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.
18 Group 1: Generally, Group 1 is set up by the distributor and contains information defined by the part number. However, although functions are defined here , do not change them without proper knowledge or they will affect perform ance of the indicator.
Locations of the switches for the Microflo are as follows: F A C E 19 P L A T E SW4 SW3 SW2 SW1 Compone nt side of board Board Edge Each switch ha s 16 posit ions, 0- 9, A, B, C , D, E, F. Operation Mode vs. Entry Mode FE: If Switch 1 is set to F and Switch 2 is set to E, the unit is in Entry Mode .
Manual Entry Mode There are two ways to access the Manual Entry Page. 1. Set Switches 1 and 2 to Entry Mo de and power up. This allows access to both groups. 2. If the Switches are not set to Entry Mode , while running under normal conditions, press the TEST/ENTER button to start the test mode.
21 The values displayed can be ad justed with the ADD/FULL toggle switch. ADD increments the value, and FULL decrem ents the value. As you hold ADD or FULL, th e scrolling rate will increase up to a maximum speed.
22 5. The K-factor values displayed can be adjusted with the ADD/FULL toggle switch located at the lower right corner. ADD increments the value, and FULL decrements the value. 6. Move the REM/USED switch at the upper right corner to the USED position to move to page “r” for the right engine in twin engine aircraft and repeat Step 5.
23 Display Description *L xxxxx = Left K-factor (wher e xxxxx is valid from 0 to 20,000. These are in 10s. A setting of 1234 would be a K-factor of 12,340) *R xxxxx = Right K-factor (as above).
