Abstract:
1. A method of calibrating a self-serve drink blending device, comprising: providing a drink blending device having a blend chamber, at least one product source, a water source, and a liquid level sensor associated with the blend chamber; operating the water source to fill the blend chamber with water until a liquid level is sensed with the liquid level sensor; determining a fluid flow rate of water into the blend chamber based on a pulse count required to reach the liquid level with water; emptying the water from the blend chamber; operating the at least one product source to fill the blend chamber with a first product for a predetermined product flow time; operating the water source to deliver water into the blend chamber to mix with the first product until the liquid level is sensed with the liquid level sensor; determining a fluid flow rate of the first product into the blend chamber based on the product flow time and a water pulse count required to sense the liquid level of mixed water and the first product with the liquid level sensor.
