The next time the aircraft is flown in cruise, turn on the boost pump. Verify that the K-factor is set properly and that there is not a 90° fitting within 3″ of the inlet. Why are the fuel flow readings inaccurate? Fuel must flow into the transducer through the side of the transducer marked “input”. Verify that the K-factor is set properly and that the transducer is not installed backwards. Why are the fuel flow readings 50% of what they should be? Contact Technical Support Department to confirm applicability. Yes, depending on the serial number of your indicator. The Digiflo adjustment is located on the back of the indicator though a small access hole which may be turned counterclockwise to increase the minimum intensity.Ĭan a standard Fuel Management System (i.e., Digiflo, Miniflo, or Microflo) be converted into one that can be interfaced with my GPS to show fuel required to destination, fuel reserve upon reaching destination, and nautical miles per unit of fuel? If so, how much will it cost? ![]() The Miniflo brightness is adjusted by turning the potentiometer located at the side/rear of the unit counter clockwise to increase the minimum intensity. The Microflo is adjustable with the toggle switch marked “Bright” on the front of the indicator. Refer to the Operating Manual for details.Ĭan the brightness level on my Fuel Flow Management Indicator be adjusted? Verify that the configuration is set for carbureted not injected. Why are the fuel flow readings erratic on a carbureted engine? Contact Shadin Avionics Sales for details. Floscan) transducer is installed, a magnetic shield may be installed directly over the transducer. There may be EMI noise affecting the fuel flow signal (e.g., magnetos or generator/alternator). Why does the fuel flow read intermittently high? Ground the shielding on the indicator side only. The unit must be pulled from the panel to access the switch that is used to put the flow meter into Group I configuration mode. ![]() ![]() Refer to Manual Entry Mode section of the Operating Manual. How do I change the K-factor on my flow meter? The flow meter steps down the voltage and provides it to the transducer. My aircraft is 28 VDC and the transducer is 12 VDC.
