At a time when fuel prices are rising globally the most urgent task is fuel monitoring. Fuel monitoring systems are developing, and GPS vehicle tracking systems too, and now appeared to the synthesis of both systems.
Fuel monitoring systems receive the information remotely and in relation to the coordinates and time.
Application of techniques of fuel monitoring allows vehicle tracking systems to dramatically increase the functionality, providing the user with information not only about the location and speed of the vehicle, but to answer a wide range of issues relating to fuel monitoring:
• Fuel tank fueling control.
Fueling control gives user of GPS vehicles tracking system to monitor where, when and how much fuel was filled into the tank; it avoids the manipulation of fuel and, consequently, reduces the operating costs of transport.
Information on raising or lowering the level of fuel comes from fuel level sensor
, and vehicles tracking system with the help of GPS determines the location and time. The volume of fueling is determined using the calibration table that is either in a terminal of vehicle tracking system, either in the software of vehicles tracking system. It should be noted that the algorithms for identifying of refills and determining their volume are quite complicated; and we are ready to provide the system designer of automobile tracking system of these algorithms to be integrated into terminal or server software.
• Fuel theft control.
Fuel theft control is carried out technically similarly to fueling control. Terminal of vehicle tracking system receives dаta about changes of fuel level in the tank from fuel level sensor. User of vehicle tracking system knows about the unauthorized fuel draining almost immediately.
• Measurement of the actual engine fuel consumption.
To solve this task fuel flow meter, fuel level sensor and/or dаta, derived from the CAN bus of a vehicle are used.
• Driver quality control.
With fuel monitoring you can detect violations of technology, such as reduction of burying of plow on a tractor or decreasing of duration of heating burners. Fuel tracking provides exact information about real fuel consumption and prevents fuel draining, fuel fraud and fuel over consumption.
• Monitoring the technical state of machines.
Knowing the information about the current fuel consumption, the driver can select the most economical way of working. The increase in fuel consumption may be a sign of engine wear.
• Time control of the engine.
Typically, GPS vehicle tracking systems determine motion time of a vehicle. However, considerable amount of machines, especially special, works without movement. In this case the automobile tracking system may determine the engine by connecting to the sensor of engine speed . However, it is easier to use a fuel flow meter DFМ. Flow meter also receives information about fuel consumption, and the time of the engine, because only running engine consumes fuel. Moreover, the magnitude of fuel consumption can also be judged on the regime of load on the engine. Knowing the fuel consumption at idle, average and maximum fuel consumption, automobile tracking system can accurately calculate the time of the engine in a particular mode.
• Axle load control
This function is not directly related to fuel monitoring, but ties the fuel information to the load of machine. Thus, user receives separate information about fuel consumption of an empty and loaded car. In addition, GPS vehicles tracking system gets valuable information about the location and time of events of loading and unloading machines, and it is necessary for effective fleet management. Information about the actual load on the axis to avoid fines for overloading and abandon reinsurance short shipments.
Fuel monitoring sensors for vehicle tracking systems
|Fuel level sensor DUТ-E
||Designed to measure the fuel volume in tank. There are number of modifications of various length and interfaces.
Compatibility requirements: terminal of vehicle tracking system should have one or two analog inputs or RS 232 interface or RS 485 interface or CAN interface.
|Fuel flow meters
|Designed to measure the flow in the fuel line of engine. Produced as one-way (direct) fuel flow meters, and differential fuel flow meters. There are versions for different ranges of fuel consumption.
Compatibility requirements: terminal of vehicle tracking system should have one or two frequency inputs.
