Flexibility


The Flow Consultant is a modular design. Each segment of our program is compartmentalized for total design flexibility. Users can change any design element without any down time to recompute.
For example, modify the Beta Ratio or Pipe Size to immediately update the FlowRate or vary the FlowRate for immediate change to the Beta Ratio.

Standards and Reference Texts


AGA8
Detail Method, Gravity Method and Heating Value
AGA3
Accepted US standard for the use of orifice meters used to meter natural gas and other fluids.
ASME3M
Accepted standard used by many industries for the metering of many fluid and in particular steam and water flow measurement.
ASMEPT6
For Throat Tap nozzles
ANSI 2530
The American National Standards Institute's (ANSI) standard that duplicates AGA 3
ANSI 2530/AGA3/ Buckingham/Spink
The original AGA/ANSI/ASME standard for the metering of fluid with the flange tap orifice Flowmeter. Once widely used by all US industries in designing flow measurement equipment, this standard has been superseded by the above reference documents.
API Chapter 14
The ANSI standards for the metering of Natural gas.
ISO5167 * The International Standards Organization's (ISO) Standard, now in three parts, for the metering of all fluid using Orifices (all tapings), Nozzles, and Venturi Meters.
Miller (1983 to date)
NX19
SGERG Equation of State for Natural Gas is widely used in Europe for custody transfer measurements. SGERG requires input of the heat content BTU (Joules), the relative density (Specific Gravity) and the mole fraction of carbon dioxide.
Spink (1935 to date)
Important Notice
Regarding ISO 5167, ASME 3M, and AGA/API/ANSI 2530
From R.W. Miller
In April 2004 ASME approved separate standards for Orifice, Nozzle, and Venturi Flowmeters. There is a major change to the
 Orifice Discharge coefficient computational equation for all tappings
 The Gas Expansion factor equation for all tappings
ASME3M and International standard ISO 5167 now use identical equations.
Other US standards (API/AGA/ANSI) no longer agree with International practice for either calculation.
Only The FLOW CONSULTANT software contains the new equation.


Fluid Properties


Only The FLOW CONSULTANT ™ software solves for fluid properties modules using the exact solution and not the generalized state equation used in most software. These solutions can be in error by several percent or more.
The Fluid Properties modules contain equation constants for computing the properties for hundreds of fluids. Fluid Properties constants The FLOW CONSULTANT ™ are maintained in accordance with all the current reference texts and standards.
Enter only Pressure and Temperature to compute Base Compressibility, Base Specific Gravity, Base Density, Flowing Compressibility, Flowing Density, Flowing Specific Gravity, Liquid Compressibility, Viscosity or the Isentropic Exponent.
Enter your own fluid properties through our custom fluid screen.

Units


US and SI units can be interchanged and modified at any time without the time consuming task of recalculating.
The Flow Consultant operates on SI units. Converting existing data is automatic when units change.
Storage of user defined templates allows for infinite unit combinations with just one click of the mouse.
All units are verified to industry standards for the current design conditions.
If you don't find your units in our software, contact us and we will add it.


Special Factor Corrections


Mercury Meters
TwoPhase Flow/MultiComponent Flow using either the James or Murdock flow rate computational solution
Drain and Vent Hole

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. The Standard graph is exported to Microsoft Excel™ via the Export Excel Function.
First you select the number of points to compute then the screen displays:
1. Scaled flow rate as a function of the differential
2. The exact flow rate corrected for the discharge coefficient and gas expansion factor for flow rate
3. The directional Bias error between actual and scaled flow rate at the measured differential.


Engineering Results


Review the Stress data, deflecting and estimated bias error when printing your datasheets.


Data Storage


The Flow Consultant is backed by proprietary Microsoft Access ^{TM}. Our software provides a utility to create and maintain multiple databases for easy to use, directory based storage. Create a new data warehouse by simply picking a name and destination.
Create custom external data objects with The Data Exporter. The Data Exporter creates user defined Microsoft Access ^{TM} tables export to spreadsheets, corporate databases or any other means of analysis.
Using the Data Exporter, share data with Microsoft Excel ^{TM} spreadsheets.


ISA DataSheet for Microsoft Excel ^{TM}


Data is exported to an Excel worksheet in the ISA format.
This puts the full capabilities of Excel graphical and mathematical capabilities at your fingertips. Included on the standard printout is a data and graphical showing dp vs flowrate.
Or Modify the ISA format data sheet to create a custom company specific worksheet.
Standardized ISA Datasheet ships with the application.
Requires MS Excel^{TM} licensing (not included).




Our simplified interface for entering mole fraction percentages solves the often cumbersome detail method solution.
Use the Detail dropdown list box to select from previous calculations or the examples to quickly populate the percentages.
The FLOW CONSULTANT ™ is preconfigured with examples from the AGA8 Standard.
Select the fluid components you want, fix on certain values and normalized the unselected components.


AGA8 Fluid Inputs (Mole Fractions)


Argon, CO, CO2, Ethane, H2, H2S, iButane, iPentane, Methane, N2, nButane, nDecane, Helium, nHeptane, nHexane, nNonane, nOctane, nPentane, O2, Propane, Water.


Gas Mixtures


Developed by R.W. Miller, the Gas Mixtures interface expands the AGA8 interface with additional fluids not included in the AGA8 standard.


In addition to AGA8 Fluid Inputs:


Acetylene, Air, Ammonia, Butylene, Chlorine, cis2Butene, Ethene, IsoButene, Propene, trans2Butene.


Also includes:


SGERG Heating Value, Gravity and CO2
AGA8 Heating Value, Gravity and CO2
AGA8 Gravity, N2 and CO2


Pipe Sizes


Select from all standard pipe sizes or manually enter pipe size.
The thermal expansion factor is calculated by selecting from these pipe materials and primary element materials:
Carbon Steel
ChromeMoly Steel
Stainless Steel (300, 304, 316, 321, 400)
Duplex
Super Duplex
Hastelloy B
Hastelloy C
Inconel X, annealed
Inconel, 624
Haynes Stellite
KMonel
Monel 400
Titanium
Tantalum
PVC
Enter the Thermal Expansion Coefficient for pipe material and primary element material if your materials are not in the pick list.
Existing Flow Consultant users may note some older materials are no longer listed. These can still be used by Entering the Thermal Expansion Coefficient. Removed materials were Yellow Brass, Beryllium Copper, Cupronickel and Pyrex Glass. If you are upgrading data from older versions of the Flow Consultant, these will default to entering the thermal expansion coefficient.


Noise Calculation


The ISA SP1, SP2, etc are ISA standards compatible or identical to the work on noise done by Hans Bauman, Masonelian for control valves.
This work is considered the basis for the most practical solution for noise on restrictive devices available in the literature. It is the source document for the solution used for the Flow Consultant noise calculation.


Restrictive Orifice


An independent review of our competition's software shows the following:


Printing


Users can suppress or print any warnings or error messages generated during the computational process.
Our detailed specification sheet can be completely customized by using the Data Exporter.
Includes a customizable ISA style datasheet.
Print Screens Shots directly from The FLOW CONSULTANT ™ without going into a separate application.
Print Preview window is now available.


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 FlowRate
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.
