NOTE
With gas or vapour
process fluid, the instrument
must be positioned higher than
the pipe inlet (see Fig. 8). With
a liquid process fluid, the in-
strument can be positioned
higher or lower, indifferently
(see Fig. 7 and 8). In this case,
during set point calibration the
negative or positive head
must be taken into account.
(Distance h in Fig.7 and 8).
