The Conductive plate (22) and insulation layer (23) are located in the cylinder (21) and curved around the inner wall of the cylinder (21). The conductive plate (22) is connected through a connecting plate (24) to the PCB board (25) and both are placed at the outside bottom of the sample taking cylinder. The PCB board (25) has a capacitor chip interface, noise processing module, capacitor digital conversion module and microcontroller I. Conductive board (22) is connected with microcontroller I through capacitor chip interface, noise processing module and capacitor digital conversion module to measure capacitance cycle. The output terminal of microcontroller 1 is connected to the data processing control board. A standard set of capacitance data formulated from measuring a range and variation of compounds, elements, and liquid mixtures are stored in the cloud server. The capacitance recorded from the measuring system is compared against the on-line standard data. The capacitance is measured as electricity conducted through the conductive plate (22) that generate electrical fields. The PCB circuit board (25) determine the charge and discharge cycle of the conductive plate (22), the charging time and generating time, and to find the capacitance of each component in the mixture.

The insulating layer (23) design is crucial in the effective reduction of conductivity interference and input to the measurement results. Depending on the material that make-up of the insulation layer (23) and thickness, between 10%-95% of capacitance different are usually noticed comparing to traditional method of measurement.

The Insulation layer (23) is made of inert material, such as PTFE or PI film, which is hydrophobic and oil-thinning. Its thickness is 10-1000 um. By adjusting the thickness of the insulation layer (23) relative to type of mixtures and the components to be measured, it can be designed to measure different level of accuracy. The customization and design of the insulation layer (23) will determine how sensitive the measuring system can be constructed and how precise the measurements are needed.
