Endress+Hauser Cerabar M PMC51 Brief Operating Instructions page 12

Installation
Pressure measurement in gases
Mount the Cerabar M with the shutoff device above the tapping point so that any condensate
can flow into the process.
Pressure measurement in vapors
• Mount the Cerabar M with the siphon below the tapping point.
• Fill the siphon with liquid before commissioning. The siphon reduces the temperature to
almost ambient temperature.
Pressure measurement in liquids
Mount the Cerabar M with the shutoff device below or at the same level as the tapping point.
Level measurement
• Always install the device below the lowest measuring point.
• Do not install the device at the following positions:
• in the filling curtain
• in the tank outlet
• in the suction area of a pump
• at a point in the tank which could be affected by pressure pulses from the agitator.
• The calibration and functional test can be carried out more easily if you mount the device
downstream from a shutoff device.
