Fuel-Flow Meter The fuel-flow meter measures the amount of fuel delivered to the engine. During engine testing procedures, the fuel-flow to the engine can be measured by three different methods: a direct flow meter, a pressure-based ... calibrated tubes located in the control room. The tubes are of various sizes to indicate different volumes of fuel-flow. Each tube contains a float that can be seen by the operator, and as the fuel-flow through the tube…

called, integrate global positioning satellite (GPS) location information. [Figure 14-79] Aircraft with fully digital flight decks process fuel flow data in computers and display a wide array of fuel flow related information on demand. Relatively new types of fuel ... aircraft. One type of device found in home-built and experimental aircraft uses a turbine that rotates in the fuel flow. The higher the flow rate is, the faster the turbine rotates. A Hall effect transducer is used to convert…
