Abstract
A home soda machine includes a cylinder of gas suitable for carbonation, an attachment mechanism to attach a bottle of water, a valve opening mechanism to open a gas release valve on the gas cylinder and introduce the gas to the bottle of water, a gas release sensor to sense at least events indicating the opening and closing of the gas release valve, and an indirect gas meter to at least determine an amount of the gas released from the cylinder based at least on a cumulative length of time the gas release valve was open as per data received from the gas release sensor.
