Abstract: A valve includes a body having an upstream port to measure upstream pressure and a downstream port to measure downstream pressure, both ports configured re a common axis, and includes a ball arranged in the body to rotate re the common axis between open and closed positions to allow for fluid flow/non-fluid flow. The ball has a calibrated member having a calibrated orifice to allow fluid flow and has a flow coefficient, an upstream pressure tap located upstream of the calibrated orifice and in fluidic communication with the upstream port to measure upstream pressure when in the open position, the upstream pressure tap angled re the common axis, and a downstream pressure tap located downstream of the calibrated orifice and in fluidic communication with the downstream port to measure downstream pressure when in the open position, the downstream pressure tap angled re the common axis, so conditions of fluid flow are 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.
