A carbonator for a beverage dispenser is characterized by a carbonator tank that is placed at a generally inaccessible first location in the beverage dispenser. Liquid and CO2 are supplied to the tank to carbonate liquid in the tank and carbonated liquid at an outlet from the tank is delivered to a beverage dispensing valve. To control delivery of liquid to the carbonator tank and thereby the level of liquid in the tank, a liquid level sensor is fluid coupled to an interior of the tank and is placed in the beverage dispenser at a generally accessible second location that is remote from the first location and from the tank. Placement of the liquid level sensor remote from the carbonator tank and at an accessible location facilitates its repair and replacement.
