Upper display
Defines whether
total
or
rate

shown on the upper display. The other
variable may be shown on the lower
display, providing the lower display is
on
in function

display. It can show the selected flow
variable briefly alternating with the
display identification, permanently
display the identification of the upper
display or it may be disabled.
Select:

dP
Decimal points
Defines the position of the decimal point
in both the rate and total displays.
See section 6.12
FACtor-A
Input A flowmeter K-factor *
Each input of the rate totaliser is divided
by
FACtor-A
or
factor-b
, which are
usually set to the K-factor of the
flowmeter, thus converting the flowmeter
output into engineering units.
FACtor
may be adjusted between 0.0001 and
99999.
When the 16 segment lineariser ‘Lin’ is
selected in the
Function
sub-menu, up
to 16 values for
FACtor-a
may be
entered, each starting at a specified
input pulse frequency to compensate for
errors resulting from flowmeter
nonlinearity..
See section 6.13 & Fig 9
5CALE
.
t-A
Total Scale Factor *
5CALE-t
is a dividing factor that converts
the pulse output from
FACtor
into a total
with the required engineering units. e.g.
if the output from
FACtor
is one pulse
per litre and the total display is required
in thousands of gallons,
5CALE-t
should
be set to 4546.1 which is the number of
litres in 1,000 imperial gallons.
5CALE-t
may be adjusted between 0.0001 and
99999.
The total flow display is independent of
the rate display.
See section 6.14 & Fig 9
5CALE
.
r-A
Rate Scale Factor *
5CALE-r
is a dividing factor that converts
the pulse output from
FACtor
into a rate
with the required engineering units. e.g.
if the output from
FACtor
is one pulse
per litre and the rate display is required
in gallons,
5CALE-r
should be set to
4.5461 which is the number of litres in
an imperial gallons.
5CALE-r
may be adjusted between
0.0001 and 99999. The flow rate
display is independent of the total flow
display.
