FQ-2100DP
Fuel Flow Measurement
The FQ-2100DP Fuel Consumption Measurement System allows measuring fuel mass and volumetric flow rate continuously over the whole measurement range from 0.2…220 l/h (optional 0.5…300 l/h) with high accuracy.
The FQ-2100DP can be applied to any engine, powertrain and vehicle test stand used for R&D, quality management, and production; and is an important tool for the development of internal combustion engines. The availability of standard as well as highly dynamic interfaces ensures easy integration into test automation systems. All components included in the system are manufactured to proven industrial quality standards and are available from multiple sources.
- High measurement accuracy over the whole measurement range
- For all established liquid fuels including Ethanol up to 100%
- Optional fast data exchange with 100 Hz ( EtherCat, CanOpen)
- Easy integration via standard interfaces
- Easy, engine-specific adjustment of parameters like fuel pressure, temperatures, and circulation rates for a wide range of applications
- Automated fuel change and venting routines
- Continuous evaluation of statistical characteristic values
- User friendly touch panel
Fuel Conditioning
Integrated pumps and temperature control system ensure an accurate temperature level for measuring and for the engine fuel circuit. Installed control modules enable the operator to adjust fuel pressures and circulation rates in correlation with given, engine-specific parameters. An optional heating module makes fuel outlet temperatures up to 60 °C possible. An optional vacuum controller adjusts outlet pressures down to -0,5bar relative. For pressures above 1 bar relative, an optional fuel inlet regulator adjusts the customer’s fuel supply pressure to the required FQ-2100DP system pressure.
A control unit with an operator touch panel directly integrated into the system ensures handling of the FQ-2100DP. This unit gives a quick and easy system overview and reports the current measurement data and parameter settings. A remote control option via various standard interfaces makes integration into test automation systems possible.

* Depending on cooling water
** Depending on heat returned by engine
*** Max. heat transfer from engine: 2kW
**** Typical -0.1...1.5 bar: the return pressure is depending on the additional pressure loss in the return pipe caused by the circulation volume and the Diameter of the pipe. There is the possibility of gas Evolution in the fuel if the return pressure is to low adjusted.
