Fuel monitoring system is used as a standard fuel level sensor as an additional sensor to be used with tank monitoring systems. Fuel Monitoring System monitors and Records fuel resource in fleets and other machineries automatically through GPS technology. Amount of fuel consumed by vehicle is reported to a web server system acknowledging accurate details on propellant dispensed. Tracer – FMS is designed for precision measurement in varied kinds of vehicle tanks, also in vats of fixed installations. Standard sensor or an additional measuring device is used for tank monitoring or vehicle tracking systems.  Automated system effectively analyses flow in fleet for all types of energy resources like petrol, diesel, LPG etc thereby balancing economy spent. GPS enabled system monitors and reports fuel level along with location, distance travelled per day through which calculation of consumed energy becomes transparent.
