Tap into a Wealth of Knowledge




The FLOW CONSULTANT ™continuously monitors input throughout the computational process. Warnings are issued and default data displayed for entries outside the manufacturer's recommendations or published standards.
Constants are built in for virtually every model of Orifice Plate, Nozzle or Venturi are included. Solve for Liquid, Gas and Vapor fluid states.
Exclusive engineering features include continual checks for Cavitation or Flashing Flows, Critical (Choked) FlowRate Computations, Restrictive Orifice Computations, Energy and Overall Pressure Loss and unique solutions derived by R.W. Miller for computations outside standard limits.

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 Once widely used by all US industries in designing flow measurement equipment, this standard has been superseded by the above reference documents.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 (2003)*
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)
ImportantNotice
Regarding ISO 5167, ASME 3M, and AGA/API/ANSI 2530
From R.W. Miller  April 2004
ASME has recently 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.

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.

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 so converting existing data is automatic.
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.

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.

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:
 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 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.
