No. The 8619’s batching capabilities differ slightly than that of the 8025 or 8035 batch controller. The 8619 features a “Volume Dosing” function which is based on time whereas the 8025 or 8035 batch controller is based on the volume counting down to zero. With the 8619’s “Volume Dosing” function, one specific volume set-point is programmed into the device and once that volume set-point is reached, the 8619 then sends a command signal to open a valve and start the dosing based on a pre-programmed amount of time. Once that time expires, the command signal stops along with the dosing, the count up to the set-point starts again and the process repeats. This type of “time” based dosing is used typically in cooling tower applications.
The 8025/8035 batch controller on the other hand simply works by entering various volumes. A button is pressed on the keypad or an input signal is sent to the electronics to engage the relay and therefore opening the valve that is controlling the flow stream. This starts the countdown to zero. Once zero is reached, the relay disengages, closing the valve and stopping the flow. The process must be repeated manually.
