Abstract: A valve includes a body having upstream and downstream ports to measure upstream and downstream pressures and configured on a common axis, and a ball arranged in the body to rotate re the common axis between open and closed positions to allow for fluid flow and no fluid flow. The ball has a calibrated member having a calibrated orifice to allow fluid flow and has a flow coefficient and upstream and downstream pressure taps located upstream and downstream of the calibrated orifice and in fluidic communication with the upstream and downstream ports to measure upstream and downstream pressures when in the open position and angled re the common axis, so a direct flow measurement of fluid flow is determined based on a measured pressure differential between upstream and downstream pressure taps re the flow coefficient of the calibrated orifice when in the open position.
