AirRate XT

Air mass flow measuring system able to operate in altitude simulation

FEV has developed the AirRate that meets all current demands concerning a state of the art measuring system for combustion air mass flow. The measuring principles of the AirRate are based on contactless measurement of gas velocity, pressure, temperature and humidity and provide the actual combustion air mass flow in kg/s.

The ultrasonic gas flow meter with four measuring paths enables a high accuracy air mass flow metering over the whole measuring range. The very fast response time of the system assures reproducible test results, even during high dynamic engine test cycles. The low-pressure drop of the system does not influence the engine behavior.

The newly developed AirRate XT is based on the AirRate DN100 and enables operation within a pressure range of 450 to 1300 hPa and temperature range from -40°C to 50°C. This also enables the AirRate XT to operate in the field of altitude simulation. The FEV-AirRate XT is easy to install because of the very compact size of the unit.

Due to the integrated flow rectifier, the FEV-AirRate XT can also be mounted directly behind a pipe bend without increasing the steadying length.
