• 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.
• The Deltapilot M must also be insulated in the case of media that can harden when cold.
Pressure measurement in gases
Mount the Deltapilot M with the shutoff device above the tapping point so that any con-
densate can flow into the process.
Pressure measurement in vapors
• Mount the Deltapilot M with the siphon above 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 Deltapilot M with the shutoff device below or at the same level as the tapping
point.
