VEGA VEGADIF 55 4 … 20 mA_HART - Manual (Page 62)

I
n mode "Flow", the instrument determines a volume or flow value out
of the measured differential pressure. The differential pressure is
generated by means of effective pressure transmitters such as e.g.
impact pressure probes or orifices and depends on the volume or flow.
F
our flow modes are available; volume flow, standard volume flow
(E uropean standards), standard volume flow (American standards)
and flow.
T he VEGADIF 55 software is also equipped with two sum counters.
T he sum counters sum up the volume or flow. For both sum counters,
the counting function and unit can be adjusted separately. The first
sum counter (sum counter 1) can be reset to zero at any time whereas
the second (sum counter 2) sums up from the setup to the flow and
cannot be reset.
Information:
A Q
uick Setup menu is available for the modes pressure, level and
flow leading you through the most important basic functions. With the
setting in the parameter MEASURING MODE you determine which
Q
uick Setup menu is displayed, see also chapter "Select language
and mode".
F or flow measurements you select via the parameter MEASURING
MODE the option "Flow", see chapter "Menu schematic".
