Adjusting Flow Rates

Flow rates of the water and syrup are adjusted based on the desired ratio. For example: if the desired
ratio is 5:1, then the flow rate of the water is 5 times that of the syrup.
If the desired finished drink total flow rate is 3.0 ounces per second, then the water flow rate is 2.5 oz./
sec and the syrup flow rate is 0.5 oz./sec. (The water at 2.5 oz./sec is five times the 0.5 oz./sec syrup flow
rate.)
NOTE: Always adjust water within its range.

Calculating Flow Rates

The most frequent ratio is 5:1. The charts above list the breakdown for many ratios and flow rates. It is
useful to be able to calculate flow rates when a chart is not available.
An example of calculating the water and syrup flow rates given the finished drink flow rate and the water
to syrup ratio:
Given:
1. Finished Drink Flow Rate = 3.0 oz./sec.
2. Water to Syrup Ratio = 5 to 1
To calculate Water Flow Rate:
1. Calculate the Total Portions = Water Portion + Syrup Portion
(example 5 + 1 = 6)
2. Calculate Syrup Flow Rate = Finished Drink Flow Rate ÷ Total Portions
(example 3.0 oz./sec ÷ 6 = .5 oz./sec)
3. Calculate Water Flow Rate = Finished Drink Flow Rate – Syrup Flow Rate
(example 3.0 oz./sec - .5 oz./sec = 2.5 oz./sec)
Prove the calculation is correct by adding water flow rate of 2.5 oz./sec + syrup flow rate of .5 oz./sec =
finished drink flow rate of 3.0 oz./sec.
Water flowing at 2.5 oz./sec and syrup flowing at .5 oz./sec achieves a ratio of 5:1 and 3.0 oz./sec. flow
rate.

Syrup/Concentrate

Syrup should always be precooled before setting the ratio. Syrup takes a path through the valve
parallel to the water path. It is introduced in the block, travels through a syrup flow control, banjo, valve
head and out the nozzle. Note, concentrate is not cooled.
High sugar syrups are more viscous (thicker) than diet syrups and consequently have more
pressure drop within a system. This pressure drop results in less flow at the valve and therefore a slower
fill time. Increasing the pump pressure will help overcome the pressure drop caused by high sugar
syrups.
