The CBF-102 Combiflow is a signal control device that conditions and scales the signals from two digital flow sensors and combines them into one scalable digital output. 

The Combiflow device is compatible with all CST flow sensors and most other two wire sensors producing a square or sine wave output proportional to rate of flow. It is not compatible with Hunter HFS sensors.


The CBF-102 produces a single square wave output combining the total rate of flow of the input devices. The input devices do not need to be of equal size nor from the same manufacturer.

The output signal may be programmed to match the output of one of the connected flow sensors, another larger flow sensor or a custom value. Programming software is available as a free download from the CST website. A micro USB cable connects the programming device to the Combiflow. 

The Combiflow features LEDs to indicate operating status and aid in diagnostics.
