Abstract
A method for calibrating flow meters measuring fluid passing through a pipe wherein fluid pressures are detected and used to determine a volume or mass flow rate using an energy correlation calculation. The energy correlation calculation equates a change in potential energy for the flowing fluid with a change in kinetic energy for the flowing fluid. The energy correlation method of calculating flow rate offers lower measurement uncertainty than calculating flow by the Reynolds number versus discharge coefficient method.
