An air measurement unit, comprises a housing (3) with one or more pressure lines (7) that lead to the measurement unit (1), a longitudinal air outlet slot (31), and an edge adjustment unit (39) for altering the slot length. The housing contains an air equalisation chamber (5) which is connected to the pressure lines. An air measurement unit, comprises a housing (3) with one or more pressure lines (7) that lead to the measurement unit (1), a longitudinal air outlet slot (31), and an edge adjustment unit (39) for altering the slot length. The housing contains an air equalisation chamber (5) which is connected to the pressure lines. The measurement unit is a high pressure unit, and the slot width is less than 200mu m, especially 100mu m. The air outlet pressure can exceed 1 bar. The nozzle lip adjustment comprises a number of members which can be adjusted mechanically, electromechanically, electrochemically, pneumatically or hydraulically. |
