Diesel Fuel Metering system (DFM) from Integra India is a versatile fuel metering system suitable for trucks, buses and diesel locomotives. The DFM system gives exact measurement of diesel consumption which helps optimise operating costs and provides savings of up to 20 percent. It helps prevent loss or waste of diesel and enables to discover and avoid fuel theft. The accurate measurement also provides a basis for analysis of fuel consumption of vehicles and subsequent actions. It can be easily and quickly installed in vehicles. The system works using the principle of connecting two flow meters on both the supply and return lines of the fuel. Differential diesel flow at supply and return lines indicates the actual and accurate fuel consumption of the engine.
