1. A method for calibrating a flow meter which is measuring the flow rate for a fluid flowing through a pipe, the method comprising the steps of:
disposing a flow restriction within the pipe;
flowing a fluid through the pipe and the flow restriction;
detect fluid pressure of the fluid at a first location within the pipe which is upstream of the flow restriction;
detect fluid pressure of the fluid at a second location within the pipe which is downstream of the first location, wherein the second location is downstream of the flow restriction and is within two inside pipe diameters (“2D”) of the flow restriction;
determine a first volume flow rate or first mass flow rate from the detected pressures, wherein the determination is done using an energy correlation calculation;
change the rate of fluid flow through the pipe;
determine a second volume flow rate or mass flow rate from the detected pressures, wherein this determination is done using an energy correlation calculation.
