To determine the map, total pressures and total temperatures are measured before and after the stage, as well as mass flow and speed. Mass flow is measured using a Venturi tube in the intake manifold. In addition to speed measurement using a tachogenerator on the engine, speed can also be measured using various trigger signals on the compressor shaft. The total temperature upstream of the compressor is measured in the 500 mm diameter inlet pipe. Downstream of the compressor, the total temperatures are recorded by four probes in the discharge line and two more probes in the collection chamber. Static pressure measurement holes are fitted along the outer contour of the impeller to follow the pressure build-up from the impeller inlet to the diffuser outlet.

In addition to these conventional measurement techniques, various optical measurement methods are used, including laser two-focus velocimetry, 2D and 3D particle image velocimetry and Doppler global velocimetry.
