Fuel consumption monitoring is one of the most important functions of a fleet management system. Reducing the operational costs can easily be achieved by reducing the vehicle’s fuel consumption.
In this section you can understand the difference between fuel level monitoring and fuel consumption monitoring reported by the engine. You can also find definitions for regularly used abbreviations and phrases.
Signal defined by FMS Standard 1.0. This is an indicator of the current level of the fuel tank. Because of the generally low precision of the sensors used by most of vehicle manufacturers it is not recommended to use solely this signal to monitor fuel consumption. It is recommended to use fuel level together with TFU or High Resolution Fuel Consumption for a precise fuel usage monitoring.
Stands for Total Fuel Used. It is a signal defined by the FMS Standard 1.0, meaning the cumulative amount of fuel burnt by the engine during its lifetime (since starting the engine).
High resolution fuel consumption
Signal defined by FMS Standard 2.0. This values is similar to TFU but in a much higher (more precise) resolution.
A power take-off or power transmission output (PTO) is a method for taking power to external devices from a running internal combustion engine. Usually it is used for driving an external mechanical device (adapter) via a mechanical shaft or in most of the cases via hydraulics. In the latter case the engine drives a hydraulic pump that provides hydraulic energy to the attached equipment (adapter) or a separate machine.
