FlavorGard™ Feature

FlavorGard™ is a patented feed back control loop that monitors the mixed product and adjusts the concentrate delivery rate to maintain a consistent mix profile, i.e. Flavor Profile. The system consists of a conductance probe mounted in the final stages of the mixing chamber, a metering pump with RPM sensor and a digital controller. Once you have completed the installation of the dispenser, entered the desired mix ratio for your concentrate, dispensed several cups of the mixed product, and are satisfied with the Flavor and Strength being delivered, simply enable FlavorGard™, (refer to FlavorGard™ in Programming the Dispenser).

The dispenser will automatically calibrate the system to all the factors that make up your particular mix profile, (e.g. water source, filtration system, Brand of concentrate and mix ratio selected, etc.).

NOTE: It is very important that you have dispensed enough product to insure that the dispenser is fully functional and you are satisfied with the Flavor Profile of the mix product before enabling FlavorGard™.

Once FlavorGard™ is enabled, the dispenser will continuously monitor the mix product as it is being dispensed and adjust the metering pump speed to maintain a consistent mixed product, thus eliminating factors such as (settling of the concentrate, tube wear, viscosity changes, liming, etc.).

The system is designed to work with in the range of variations that can be caused by these factors. The factory preset range is (+/- 10 %) and is adjustable to a Max of (+/- 15%). This insures that the FlavorGard™ system is not responding to factors that cannot be corrected by minor adjustments to the speed of the metering pump, (e.g. kinked hoses, low water pressure, severely worn tubes, empty BIB’s, etc).

NOTE: Changes to Concentrate Ratios or Dispenser Flow Rates will automatically disable FlavorGard™. You will need to re-enable FlavorGard™, once you are satisfied with the new Flavor Profile.
