The system comprises a sensor and a controller. The sensor is entered into the material being measured e.g. a fermenter or mixing vessel and is connected to the controller by special cables.
The size of the micro sensors is optimised for each application  and  can be  selected to give the best resolution where required for the sensor, depending on the particular application.
The system makes use of Charis proprietary IMA sensing technology (clik on) to give fouling immunity and high precision.  There are versions available for liquid only, foam only and liquid and foam tohether The level control  can manage the generation of foam to prevent overflows. Foam is controlled by means of a separate output to a pump or process adjustment carried out.
FDA approved materials are used in the construction.
