The quick setup for density-compensated level measurement is hence finished. Parameterization example VEGABAR 86 always measures pressure independently of the pro- cess variable selected in the menu item " Application". To output the selected process variable correctly, an allocation of the output signal to 0 % and 100 % must be carried out (adjustment).
