How are gas volume and flow rate calculated during the purging of oxygen pipelines?

Estimated based on piping pressure experience

SH3501 stipulates: 8.2.8 During the air purging of the piping system, the air flow velocity must be no less than 20 m/S. Given the flow velocity and pipe diameter, the flow rate can be calculated.

The general flow rate is calculated. During the construction of a project, pipelines generally do not have flow meters. Moreover, if the flow meters are inaccurate, how can it be ensured that the speed of the gas used for pipeline purging is at least 20 m/s?
