(1) Measurement of gas pressure.
The pressure intake must be located
in the upper part of the piping and the
separator above it.

It is recommended that the pressure transmitter be installed below the
separators. If the pressure of the process is less than the atmospheric
pressure, this becomes essential.
Vibrations on the capillaries can create interference with the measurement
and distort it. It is therefore advisable to install the transmitter on a vibration-
free bracket and to attach the capillaries to stable structures.
(3) Level measurement in an open tank.

must be greater than the half
diameter of the measurement
membrane of the separator flange.
If this is not the case, the measure
would not be proportional to the level
as long as the membrane is not totally
immersed.
