How to control the fuel consumption without a fuel level sensor?

Development background

The road construction company was looking for a solution for automated control of fuel consumption on equipment, in particular road rollers. Depending on the operating conditions of the equipment, the level of vibration, the slope of the site - the fuel consumption of the equipment varied from 10 liters per hour to 200 liters per hour.

Project tasks

• Real time fuel consumption control.
• Fuel economy.
• Operators' work control.

Solution

The integrator company has developed a solution that allowed the client to monitor the fuel consumption on the road rollers, as well as to control the work of the equipment operators.On the first stages of the project the specialists of the integrator company have found out that it is not reasonable to use the fuel level sensors in the project due to the curved shape of the fuel tank of the road rollers and the equipment issues that can work at a large angle of inclination.

In addition, the vibratory road roller and its vibratory unit can be connected and disconnected depending on the customer's requirements, and the fuel consumption when the unit is connected will increase. The experts of integrator company have decided to use the Technoton DFM500D CAN dual-chamber differential flow meter, which can transmit data via the CAN protocol.

Monitoring system parameters:       

• Engine temperature
• Instantaneous fuel consumption
• Total fuel consumption
• Engine runtime

 Galileosky tracking device collects the parameters controlled by the flowmeter (temperature, fuel volume, fuel consumption, etc.) and sends them to the Wialon software, which generates the report for the real-time fuel control.

Result

The advantages of the solution created by the integrator company are that the data on the fuel consumption, engine runtime in different modes is received and reported in real time. The client sees a complete and detailed report on the operation of the equipment and can assess the technical condition of the equipment and the work of the operators. The obtained data helps the client employees to identify the conditions that increase the fuel consumption and avoid them.
