Embodiments include a Selective Catalytic Reduction (SCR) system including at least one catalyst, a differential pressure (dP) sensor operably coupled to the SCR system, a temperature sensor, and a controller. The dP sensor is configured to measure a pressure differential across the SCR system, and determine a first output value from the dP sensor and a first temperature output value from the temperature sensor. The first output value represents a pressure differential value across the SCR system. The first temperature output value is indicative of a temperature of the SCR system. The controller is further configured to estimate an exhaust mass flow output from the aftertreatment system using the first output value from the dP sensor and the first temperature output value from the temperature sensor.)
