Mounting location

5.4.1 Pressure measurement
Functional testing can be carried out more easily if you mount the device downstream
from a shutoff device.
Pressure measurement in gases
Mount the device with shutoff device above the tapping point so that any condensate can
flow into the process.

Pressure measurement in vapors
For pressure measurement in vapors, use a siphon. The siphon reduces the temperature to
almost ambient temperature. Preferably mount the device with the shutoff device and
siphon below the tapping point.
Advantage:
• defined water column causes only minor/negligible measuring errors and
• only minor/negligible heat effects on the device.
Mounting above the tapping point is also permitted.
Note the max. permitted ambient temperature of the transmitter!
Take the influence of the hydrostatic water column into consideration.
