Insertion Flow Meter Calculations

Flowing Velocity

Volume Flow Rate

= V

Mass Flow Rate

= V

Aρ

Where:

A = Cross sectional area of the pipe (ft^2)

f = Vortex shedding frequency (pulses / sec)

= Meter factor corrected for Reynolds Number (pulses / ft)

= Volume ow rate (ft^3 / sec)

= Mass ow rate (lbm / sec)

= Flowing velocity (ft / sec)

= Density (lbm / ft^3)
