Calculating CFM from Air velocity?

I'm building an air flow bench to test internal combustion engine components and people typically use pitot tubes to measure water pressure and then use that pressure to calculate air velocity, and then from that calculate CFM. However, Can I just use an air velocity meter instead? Then from that calculate... show more I'm building an air flow bench to test internal combustion engine components and people typically use pitot tubes to measure water pressure and then use that pressure to calculate air velocity, and then from that calculate CFM.
