UPDATE!!! Actual flow rates for 3/16 accuflex bev seal 235 ultra for soda

[born2dive9702]

Helllo everyone, I hope you find this information useful, I have been looking for the flow rates for 3/16 accu flex bev seal ultra 235 for soda. No one seemed to know what the accurate flow rates of this line were so I spent a day measuring different lengths for kegging soda and pushing it thru a beer tower.

Here is the data.
Kegs are carbonated and pressurized to 23 psi. and at 3.6GV
Top of the Keg to the top of the tower is 22.75"
The product lines inside the beer tower are 5/16" stainless steel tube.
Line used, 3/16" Accuflex Bev-seal ultra 235
Lines were on a horizontal coil laying on the top of the corny kegs
30 oz Amount of fluid measured in XX seconds
cola chilled to 35.6 degrees F

Length of fl/oz time to fill flow rate
hose in feet measured sec oz/sec
3 30 16.1 1.863
6.5 30 17 1.764
13 30 20.5 1.463
19.5 30 24 1.25
26 30 27 1.111
50 30 35.7 .8403

pressure 23 psi, 30 oz measured in XX seconds Same settings as above but with 5.25" mixing sticks installed in dip tube
1mix 2mix 3mix 4mix
sec oz/sec sec oz/sec sec oz/sec sec oz/sec
3 25.07 1.197 29.39 1.021 33.63 .892 36.33 .826
6.5' 25.25 1.188 29.65 1.012 32.78 .915 36.22 .828
13 27.8 1.079 31.53 .951 35.65 .842 38.17 .786
19.5 30.12 .996 34.7 .865 38.22 .787 41.53 .722
26 32.59 .921 35.64 .842 38.7 .775 41 .732
50 40 .75 42 .714 45.8 .655 48 .625

Cola being dispensed from a tower or a faucet should be dispensed at;
Diet Cola at 36 degrees F at a flow rate .7oz/sec
Full flavour cola at 36 deg F at a flow rate of 1.25 oz/sec

These flow rates are for ideal dispensing without/ low amount of foam forming in glass. These rates have been verified by Cornelius.
Faster flow rates will cause cavitation in the line causing excessive foam in the glass.

Maximum flow rates should never exceed
diet cola 1.5 oz/sec
full flavour cola 2oz/sec

Remember the colder the soda allows for a faster pour with less foam
Remember when cold soda hits warm faucets it will foam, the hotter the faucet is the more foam will come out.

The I deal temp for serving soda is 36.5, When measuring the temp of the soda in the glass. pour a glass and wait 10 seconds. place a thermometer in the glass. The temp of the cola should not be above 38 degrees for Pepsi, 40 degrees for coke.

If anyone has a question or wishes for an excel table of the numbers please PM me.

I hope this information helps all those struggling with pour rates, and foaming.

Some people have been asking for some clarification of the numbers because of the formatting or lack there of in the original post. I am including an excel sheet snap shot for all to see. seen as the attachment below. All measurements have been double checked to an accuracy of +-.002 fl oz/sec. using a drip scale timer.

What is meant by mixing sticks are viewed in the photo below. They are used to mix epoxies and are about 5.5" long X about 1/4" dia. and slide into the dip tube in your corney kegs they come out normally by themselves due to the carbonation, however if they do not, when your tank is empty simply place the bung in connect your gas line adjust the pressure to 5psi and unscrew the liquid connector, they will come flying out all at once. They slow the rate of flow considerably thus allowing for a much slower pour. These are advisable to use when you taps do not have flow control. These can also be installed in the tubes of your beer tower if there is insufficient reduction in the flow rates. They are easily removed by blowing air into the tap with the tap open.

If anyone has questions please feel free to drop me a line.
