Flow Conditioning Calculator

Meter Type

Meter Size

Nominal meter bore diameter (2-30 inches)

Beta Ratio (β = d/D)

—

Orifice-to-pipe diameter ratio (0.10 - 0.75)

Upstream Fitting

Available Upstream Length

Straight pipe available upstream of meter

Pipe Internal Diameter

Actual pipe bore (for D conversion)

Flow Conditioner Type Select installed or proposed flow conditioner

Conditioner Location

D from meter

Distance from conditioner outlet to meter inlet in pipe diameters

L_req = f(meter type, β, fitting type)

L_req = Required straight-run length (pipe diameters)

β = Orifice beta ratio (d/D)

D = Pipe internal diameter

ΔP = K × ρ × v² / (2 × 144)

Frequently Asked Questions

What meter types does the flow conditioning calculator support?

It supports orifice, turbine, ultrasonic, and Coriolis meters per AGA standards for meter run design.

What does a flow conditioning calculator determine?

It calculates upstream and downstream straight-run requirements and flow conditioner specifications to ensure accurate gas measurement.

Why is flow conditioning important for gas meters?

Proper flow conditioning eliminates swirl and velocity profile distortions that can cause measurement errors in natural gas metering systems.
