Apparatus comprising: a valve having: a valve body or housing configured to be arranged in, or form part of, a piping having a fluid flow, and also configured with at least one pressure tap arranged at at least one location along the piping to allow pressure of the fluid flow of the piping to be measured; and an orifice plate having an orifice configured or formed therein, and configured to rotate in the valve body or housing on an axis of rotation positioned at a different location along the piping than the at least one pressure tap (56a'; 56b') for rotating between a first rotatable position for providing a normal fluid flow operation and a second rotatable position substantially perpendicular to the fluid flow for providing a direct flow measurement of the fluid flow, so that the direct flow measurement of the fluid flow may be determined based at least partly on signaling sensed by at least one pressure tap sensor containing information about a measured pressure at the at least one pressure tap (56a'; 56b') when the orifice plate is in the second rotatable position, characterized in that the orifice plate is configured with two tap members (56a, 56b) each having an integrated corresponding pressure tap (56a', 56b') configured or formed therein and configured to pass therethrough, wherein the tap members (56a, 56b) are configured with an angled and beveled configuration or formation, and in that the orifice plate is configured in relation to an orifice plate stem having an integrated axial pressure tap configured therein along the axis of rotation to permit one of the pressure taps configured in the orifice plate to be measured, and in that the orifice plate includes a channel portion configured with a channel to be in fluidic communication with the integrated axial pressure tap of the orifice plate stem. a valve body or housing configured to be arranged in, or form part of, a piping having a fluid flow, and also configured with at least one pressure tap arranged at at least one location along the piping to allow pressure of the fluid flow of the piping to be measured; and an orifice plate having an orifice configured or formed therein, and configured to rotate in the valve body or housing on an axis of rotation positioned at a different location along the piping than the at least one pressure tap (56a'; 56b') for rotating between a first rotatable position for providing a normal fluid flow operation and a second rotatable position substantially perpendicular to the fluid flow for providing a direct flow measurement of the fluid flow, so that the direct flow measurement of the fluid flow may be determined based at least partly on signaling sensed by at least one pressure tap sensor containing information about a measured pressure at the at least one pressure tap (56a'; 56b') when the orifice plate is in the second rotatable position, characterized in that the orifice plate is configured with two tap members (56a, 56b) each having an integrated corresponding pressure tap (56a', 56b') configured or formed therein and configured to pass therethrough, wherein the tap members (56a, 56b) are configured with an angled and beveled configuration or formation, and in that the orifice plate is configured in relation to an orifice plate stem having an integrated axial pressure tap configured therein along the axis of rotation to permit one of the pressure taps configured in the orifice plate to be measured, and in that the orifice plate includes a channel portion configured with a channel to be in fluidic communication with the integrated axial pressure tap of the orifice plate stem.
