1. A refrigerator comprising:
- a cooling system;
a dispenser coupled to said cooling system, said dispenser comprising a water valve for controlling a flow of water through said dispenser and a flowmeter for measuring the amount of water dispensed through said dispenser; and
a controller operatively coupled to said water valve and said flowmeter, said controller configured to;
receive an input relating to a target volume of water;
adjust the target volume for a volume error correction to obtain an adjusted target volume, wherein the volume error correction is based on a flow rate;
open said water valve;
determine a total volume dispensed using said flowmeter; and
close said water valve when the total volume dispensed equals the adjusted target volume.

Abstract
An appliance includes a dispenser having a water valve for controlling a flow of water through the dispenser and a flowmeter for measuring the amount of water dispensed through the dispenser, and a controller operatively coupled to the water valve and the flowmeter. The controller is configured to receive an input relating to a target volume of water, adjust the target volume for a volume error correction to obtain an adjusted target volume, wherein the volume error correction is based on a flow rate, open the water valve, determine a total volume dispensed using the flowmeter, and close the water valve when the total volume dispensed equals the adjusted target volume.

7. A method of controlling a water valve for a water dispensing system coupled to a cooling system of a refrigerator, the water dispensing system having a controller communicating with the water valve and a flowmeter, said method comprising:
-
receiving a target volume at the controller from a user interface; adjusting the target volume for a volume error correction to obtain an adjusted target volume, wherein the volume error correction is based on a flow rate; opening the water valve; measuring the volume using the flowmeter to determine a total volume; and closing the water valve when the total volume equals the adjusted target volume. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15)

16. A computer program embodied on a computer readable medium for controlling a water valve for a water dispensing system coupled to a cooling system of a refrigerator, the water dispensing system having a controller communicating with the water valve and a flowmeter, said computer program comprising:
-
a code segment that receives an input relating to a target volume of water; a code segment that adjusts the target volume for a volume error correction to obtain an adjusted target volume, wherein the volume error correction is based on a flow rate; a code segment that opens the water valve; a code segment that determines a total volume dispensed using inputs from the flowmeter; and a code segment that closes the water valve when the total volume dispensed equals the adjusted target volume. - View Dependent Claims (17, 18, 19, 20)
