Calculations
Parameters P720 to P725 are values calculated by the unit, dependent on
application, a
nd are “Read Only”, therefore have no default values.
P720 Area
Displays the calculated value of the area when, P700 = 2 BS3690 flumes and
P700 = 4 Area Velocity.
P721 Cv
Displays the calculated value for Cv when, P700 = 2 BS3680 flumes.
P722 Cd
Displays the calculated value for Cd when, P700 = 2 BS3680 flumes.
P723 Ce
Displays the calculated value for Ce when, P700 = 2 BS3680 weirs.
P724 Cu
Displays the calculated value for Cu when, P700 = 2 BS3680 flume and
P701 = 3 or 4 U-Throated flumes.
P725 Kb
Displays the calculated value for Kb when, P700 = 3 BS3680 weirs and
P701 = 1 Rectangular weir.
Breakpoints
P730-793 Breakpoints
Where the Primary Measuring device does not match any of the pre-
programmed devices contained in the FlowCERT LITE, then a universal
volume calculation can be performed. A head Vs flow chart is used, to enter
a number of
Breakpoints
for the
head
and
flow (P730-793)
, which is either
provided by the manufacturer or created based on the dimensions of the
device.
Breakpoints should be entered in
pairs
of
head
and the corresponding
flow
for that head. The
first pair
entered must be for
zero head
and
flow
and
the
last pair
entered must be for
maximum head
and
flow
. The higher
number of breakpoints (pairs) entered then the greater accuracy there will
be. There are a maximum number of 32 breakpoint pairs for head and flow
that can be entered.
