An automated liquid dispenser (10) for dispensing a liquid into an open-top container comprises: a housing (14) defining a dispensing zone for receiving the open-top of the container; a liquid dispensing spout (16) extending from the housing (14) and above the dispensing zone for dispensing liquid into the container; first and second (38) reflector arrays disposed on opposite sides of the dispensing zone such that the open-top container is between the first and the second arrays (38) when the open-top container is received within the dispensing zone, and each reflector array comprises multiple vertically-spaced reflectors (40a-40e), with a reflector on the first array being paired with a reflector on the second array; an emitter (42) mounted in a position to emit a signal onto the multiple reflectors of the first reflector array for reflection across the dispensing zone and onto the corresponding paired reflectors of the second array (38); a receiver (44) mounted in a position to receive the emitted signal reflected from the reflectors of the second array and generate a container height signal; a liquid level sensor (52) for determining the liquid level in the container and generating a liquid level signal; and a controller (54) coupled to the receiver and the liquid level sensor for controlling the filling of the liquid into the container based on the received container height signal and liquid level signal.
