SV-EMS-220 Installation and ConfigurationFuel Flow SensorThe approximate pulses/gallon setting for the Floscan 201B (i.e., cast metal casesensor) is 28,000 to 31,000. The approximate pulses/gallon for the ElectronicsInternational FT-60 (i.e., the red cube) is 68,000. You must configure the fuel flowsensor using this numerical value in the Sensor Setup Menu (SETUP MENU > EMSSETUP > SENSOR SETUP). More information on this topic is discussed in the FuelComputer Configuration section of this chapter.Floscan 201B sensor only: make note of the numbers on the tag (pulses / gallon)attached to the fuel flow sensor.<strong>Dynon</strong> <strong>Avionics</strong> supplies the ElectronicsInternational FT-60 (<strong>Dynon</strong> P/N 100403-003) fuel flow transducer. <strong>Dynon</strong> nolonger supplies the Floscan 201B, but<strong>SkyView</strong> is compatible with this sensor.The SV-EMS-220 supports differentialfuel flow sensor installations in Rotax912 and 914 installations as illustrated inFigure 33.Table 33 revisits which SV-EMS-220 pins arecompatible with fuel flow sources.Pin Wire Color Function13 or16 or BlackGround1714 YellowFuel Flow Input 1(From fuel tank)15 Red +12 volt Auxiliary19 White/BlackFuel Flow Input 2(Return to fuel tank)Table 33–SV-EMS-220 Fuel Flow PinsGeneral Placement RecommendationsWhen placing either sensor, ensure that the three wire leads are pointed straight up. A filtershould be placed upstream from the sensor to screen out debris. Placement of the fuel flowsender relative to other items in the fuel system like fuel pumps is left to the builder. It is notuncommon, though, to place the sender downstream of any auxiliary electric boost pumps butupstream of the engine driven fuel pump. The Fuel Flow Transducer, hoses and fittings shouldNOT be installed next to the exhaust system or a turbocharger. Excessive heat can damage fuelsystem components. For best measuring performance, the fuel should travel uphill by one totwo inches after leaving the fuel flow sender.Due to vibration issues, never connect the sensor directly to the engine.Do not use Teflon tape when screwing in any of the fittings.EI “Red Cube” InstallationThe Electronics International “Red Cube” FT-60 flow transducer has ¼” female NPT ports. Donot exceed a torque of 300 inch-lbs when installing fittings into the transducer. The Red Cube7-32 <strong>SkyView</strong> System Installation Guide - Revision J
