.5 Measurement setup density and interface
Density and interface measurement are carried out in level measure-
ment mode.
à Mount DPT10 below the lower isolating diaphragm
à The ambient temperature should be the same for both capillaries
Information:
The density measurement is only ensured at a level above the upper
measuring point. Homogeneous density allocation is a prerequisite.

Fig. 20: Measurement setup with density measurement. Density 1 and h = 0.3 m
means Δp = 29.4 mbar. With density change: e.g. measured Δp = 35.3 mbar
corresponds to density 1.2, measured Δp = 23.5 mbar corresponds to density
