When the pressure between the two are equal, there is no flow, due to static balance.
When the pressure in the filler bowl is less than the carbo-cooler the liquid in the carbo-cooler will flow into the filler bowl until the pressure is equalized.
If the pressure is greater in the filler bowl, liquid will flow back into the carbo-cooler until there is a pressure balance.
The Uni-Level-Trol system basically controls the pressure balance of the filler bowl in relation to the carbo-cooler (see bottom drawing).
A single float ball (E) linked to a two-lobe cam (D) which will activate two air switches which in turn will open or close one or the other of two valves.
The vent valve (A) will open or close upon demand of the float and cam assembly (D). When the level of liquid is lower than a pre-determined level, the valve will be opened by an air signal and allow the air in the filler bowl head space to be reduced. This causes a pressure unbalance (lower) and the liquid from the carbo-cooler will flow into the filler bowl.
When the bowl liquid level is at the correct pre-determined level, the valve closes and the flow stops because of the pressure balance.
This action continues repeatedly as the level decreases during the filling operation, thus replenishing the liquid in the bowl.
If for any reason, the liquid level in the bowl becomes too high the other lobe of the cam contacts the other air switch and will open the counter pressure valve (B). This valve is connected to the high pressure CO2 or air line through the rotary gland (I) of the filler and when opened will allow higher pressure air or CO2 (about 15 PSI above bowl pressure), to enter the filler bowl, thus pushing the liquid in the bowl back to the carbo-cooler. When the level is back to normal range the valve closes and the normal operation continues as before.
The control pressure for the air valves is 35 PSI, this is set by air regulator (F).
The operator can easily set the desired liquid level by rotating the cam assembly (D). Generally, the small bottles fill better with a low bowl level and larger bottles fill faster at the higher level.
The relationship of the normal operating level and the counter pressure level is fixed by the cam lobes. Thus at any pre-determined level, the vent and counter pressure operation is fixed in relation to each other.
