• Keep the pressure compensation element (1) free from contamination
• A position-dependent zero point shift (when the vessel is empty the measured value does
not display zero) can be corrected
• The use of shutoff devices and/or water pocket pipes is recommended for mounting
• The orientation depends on the measuring application
5.2 Mounting the device
5.2.1 Pressure measurement in gases
Mount the device with the shutoff device above the tapping point so that any condensate can
flow into the process.
5.2.2 Pressure measurement in vapors
A water pocket pipe reduces the temperature to almost the ambient temperature. The defined
water column only causes minimal (negligible) measured errors and minimal (negligible)
thermal effects on the device.
Observe the maximum permitted ambient temperature of the transmitter!
• Ideally, mount the device with the O-shaped water pocket pipe below the tapping point
The device may also be mounted above the tapping point
• Fill the water pocket pipe with liquid before commissioning
5.2.3 Pressure measurement in liquids
Mount the device with the shutoff device below or at the same level as the tapping point.
