Highly precise and boasting excellent temperature stability, the modular design allows them to be combined with other systems. Accurate results even at low flow rates and with short measurement times make this a dynamic and flexible solution.
Fuel consumption is determined continuously in kg/h via direct mass flow measurement. Unlike volumetric measurement methods, it is not necessary to also determine the density alongside the measurement of the gravimetric or specific fuel consumption. This allows fuel consumption to be assessed up to an accuracy of 0.12 % for the entire system under real test bed conditions.

Easy Installation
The system is designed to be easily installed for all gasoline or diesel injection systems using a specially developed pressure control system. This makes it possible to replicate realistic vehicle conditions on the testbed.
Testbed Versatility
A measurement range from 0 to 125 kg/h for engines up to 600 kW offers testbed versatility. Additionally, a calibration interval of 3 years and a built-in accuracy check compliant with ISO 9001 make this a robust and reliable system.
Measurement Accuracy
Fuel temperatures between 10 and 80°C can be preselected, guaranteeing high measurement accuracy and temperature stability. Furthermore, gas bubble separation and a bubble monitoring system ensure that the fuel supply is bubble free.
