flow_cal_error 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
