A fuel metering valve includes a valve body housing a valve element in an interior chamber between an inlet port and an outlet port, an actuator coupled to move the valve element relative to the valve body, and a controller configured to regulate the position of the valve body. The valve element regulates a flow of fuel through the valve body. The controller regulates the position of the valve body via an actuator based on a measurement by a pressure sensor to achieve a target mass flow rate of the fuel through the valve body. The pressure sensor is calibrated for accuracy only across a limited scale range based on a predetermined maximum subsonic pressure. |
