Menu GV Orifice plate shows some
GW Extremal values
of the
Orifice calculation
for
an
expanded type plate.
GW01
shows the flow rate coefficient C and
GW02
shows the Reynolds number Re
D
in the design point of the orifice meter.
GW04
and
GW05
contain the maximum mass flow rate and the maximum flow rate at base con-
ditions.
GW14
and
GW15
show the corresponding minimum values.
Figure 187: Menu GX Pipe roughness
GX Roughness of tube
influences the velocity profile and thus the flow rate depend-
ing on delta-p. If this correction is activated (
GX04
), a correction for the roughness
entered in
GX05
is considered according to GOST (see below).
Figure 188: Menu GY Abrasion of orifice edge
If "Calculation" is set in coordinate
GY04
(instead of "off" or "default"), the abrasion of
orifice edge according to GOST is factored in. For this purpose,
GY05 Point in time
of the determination of
GY06 Beginning radius
of the inside diameter of the orifice
plate must be defined.
