Pressure measurement in liquids
Mount the device with a shutoff device and siphon below or at the same height as the
tapping point.
Advantage:
• defined water column causes only minor/negligible measuring errors and
• air bubbles can be released to the process.
Take the influence of the hydrostatic water column into consideration.

5.4.2 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
– Or at a point in the tank which could be affected by pressure pulses from the agitator.
• Functional testing can be carried out more easily if you mount the device downstream
from a shutoff device.
