Level measurement

Fig. 17: Measuring arrangement for level
• 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 outflow
– in the suction area of a pump
– 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.
