A refrigerator and method utilize first and second sensors to determine a volume of fluid dispensed by a fluid dispenser that incorporates a fluid storage receptacle. The first sensor is disposed in upstream fluid communication with the fluid storage receptacle to generate a first signal representative of a volume of fluid entering the fluid storage receptacle and the second sensor is disposed downstream of the first sensor to generate a second signal representative of a volume of fluid exiting the fluid storage receptacle, and a controller determines the volume of fluid dispensed using the first and second signals output by the first and second sensors.
