Ideal for applications where precise temperature stability and control are required, they use a universal measurement system for different injection systems and engine sizes. Highly reliable, these systems help to optimize testbed use and return on investment. They support the development of highly efficient powertrains with reduced emissions.
Quick to set up and easy to integrate into your testbed architecture thanks to compatible interfaces, this system is designed with the user in mind. The result is a robust system that fits right into your existing development toolchain.

The AVL Fuel Balance system feeds fuel into the engine from a continuously weighed measurement vessel. The vessel is designed to mimic the properties of the fuel tank so that it does not interfere with accurate consumption measurement.
A highly sensitive capacitive displacement sensor, which is connected to the vessel by a beam, is calibrated with a special calibration weight. This process ensures accuracy to ISO 9001 standard and takes place automatically in just a few minutes.
Using automatic calibration in this way ensures that human calibration error is avoided, and that accuracy is maintained.
