Flow Calculation
Fault
During setup and
configuration of the
flow
algorithm
parameters,
insufficient
configuration
or invalid parameter
values have been
entered
which are causing a
division by zero math
error
in the flow calculation Carefully review the
flow algorithm
parameter
values that have been
configured. Correct
any errors. When the
flow is showing a
good value and this
status is cleared,
reset the device to
clear any Critical
Status that may have
been generated due
to the bad flow
calculation.
Parameters to check:
For Primary Elements
/ Algorithms other
than Pitot Tube
(Algorithm Option =
ASME 1989
Algorithms) and for
any Elements
(including Average
Pitot Tube, Algorithm
Option = Advanced
Algorithms)
Pipe Diameter D
cannot be equal to
Bore Diameter d
d must be > 0
D must be > 0
d < D
For primary element /
algorithm = Pitot Tube
(applicable to
Algorithm Option =
ASME 1989
Algorithms only)
Pipe Diameter D must
be equal to Bore
Diameter d
alpha_D must be
equal to alpha_d
D = d and alpha_D =
alpha_d
D and d must be > 0
alpha_D and alpha_d
must be > 0
Primary Element =
Wedge
Segment Height H <
D H and D > 0
Viscosity and Density
Coefficeints (as
applicable)
Make sure at least
one of the Viscosity
coefficients > 0
Make sure at least
one of the Density
coefficients > 0
