3.2.1 Measuring lines that need to be connected
The following points need to be observed when connecting the pressure line:
• To ensure there is no influence on the measured values, severe bends and
coils in the wire should be avoided.
• To prevent deposits, there should be a continuous incline or drop of at least
8%.
• When measuring steam pressure, a water bag-forming loop must be
provided due to the temperature (see accessories).

• The transmitter must be positioned below the measuring point for liquid
measurements. Vent the pressure line before commissioning.
• The transmitter must be positioned above the measuring point for gas
measurements.
3.2.2 Pressure surge absorption
Pulsating pressure on the system side can lead to functional problems. We re-
commend installing a damping element in the pressure connection lines as a
protective measure.
