Installation Deltapilot M 4...20 mA HART
12 Endress+Hauser
– or at a point in the tank that can 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 of a shutoff device.
• Deltapilot M must be included in the insulation for media that can harden when cold.
Pressure measurement in gases
• Mount Deltapilot M with shutoff device above the tapping point so that any condensate can
flow into the process.
Pressure measurement in steams
• Mount Deltapilot M with siphon above the tapping point.
• Fill the siphon with liquid before commissioning.
The siphon reduces the temperature to almost the ambient temperature.
Pressure measurement in liquids
• Mount Deltapilot M with the shutoff device below or at the same level as the tapping point.

• When mounting rod and cable versions, make sure that the probe head is located at a point
as free as possible from flow. To protect the probe from impact resulting from lateral
movement, mount the probe in a guide tube (preferably made of plastic) or secure it with a
clamping fixture.
• In the case of devices for hazardous areas, comply strictly with the safety instructions when
the housing cover is open.
• The length of the extension cable or the probe rod is based on the planned level zero point.
The height of the protective cap must be taken into consideration when designing the layout
of the measuring point. The level zero point (E) corresponds to the position of the process
isolating diaphragm.
Level zero point = E; top of the probe = L.
