Accuracy / Uncertainty
Calculations
The estimated uncertainty
based on the measured and unmeasured variables used in the flow
rate computation are combined in accordance with the selected
standards procedures to give the overall uncertainty (Accuracy).
The estimated
uncertainty of the discharge coefficient and gas expansion factor
is computed using the appropriate standards. The user inputs the
uncertainties of the other measured or unmeasured variables.

Flow Versus
Differential Pressure
Unique
to
The FLOW CONSULTANT ™
is the exportable (and printable) tabulation shown below. First
you select the number of points to compute then the screen
displays:
- Scaled flow rate as a
function of the differential
- The exact flow rate
corrected for the discharge coefficient and gas expansion factor
for flow rate
- The directional Bias error
between actual and scaled flow rate at the measured
differential.

Wide Range Metering |
|
|
Wide Range Metering Accuracy can now easily be
determined by
Step
1
select Flow Vs Dp to determine the +/-
Bias, errors that occur by not including changes in discharge
coefficient and gas expansion factor with Flow-Rate
Step 2
select Accuracy to determine the+/-
error at the lowest acceptable flow rate.
Combine
the bias and precision error by summation and repeat for
additional transmitters.

IAPWS Properties of Water/Steam
Since
1967, the industry standard for the thermodynamic properties of
steam and water has been the IAPWS "1967 IFC-Formulations for
Industrial Use". These formulations have been the basis for
the American Society of Mechanical Engineers (ASME) steam tables.
In
1995, The International Association for the Properties of Water
and Steam (IAPWS) released a new formulation for scientific use
called the "IAPWS Formulation 1995 for the Thermodynamic
Properties of Ordinary Water Substance for General and Scientific
Use", otherwise known as the IAPWS-95 formulation.
The
exact formulation is developed and programmed in
The FLOW CONSULTANT ™,
not the approximation region equations given in IAPWS Industrial
use version (`1997)

following web site provides additional information:

Restrictive Orifice Calculations -
clamped or free fitting
The exact plate bending equation presented in "Formulas for
Stress and Straining" (RC Rourk and WC Young, McGraw Hill,
1976) are programmed in
The FLOW CONSULTANT ™
. With the restraints presented in the standards for maximum
allowable bending, the plate thickness is calculated for
widely used restrictive orifice meters.
