A mechanical level sensor detects when a fluid material added to a chamber has reached a predetermined level and therefore comprises a predetermined particular volume. Material is added to a chamber until it has reached the predetermined level. Once this level is reached, additional material overflows into a level sensor. The overflow material causes a wheel having a plurality of wells to rotate. This rotation is detected by a control circuit that signals the cessation of addition of material to the chamber and the dispensing of the material present in the chamber. The sensor is highly sensitive due to the almost frictionless rotation of the wheel about its axle.
