I recently worked on liquid-gas and liquid-liquid interface analysis in the radio frequency domain.
In many case, chemists or industrial chemists reuse flasks, containers and reactors for many different reactions or even solvents.
This project aimed at localizing the gas/ liquid or liquid interface by using an antenna to probe the dielectrical properties of the solutions while keeping the system simple and flexible for as many solvents as possible to allow volume and/or interface height estimation.
In many cases, chemists and industrial chemists reuse flasks, containers, and reactors for various reactions or even different solvents. This project aimed to localize the gas-liquid or liquid-liquid interface by using an antenna to probe the dielectric properties of the solutions. The goal was to keep the system simple and flexible, accommodating a wide range of solvents while allowing for accurate estimation of volume and interface height.
The prototype was build around the superbe NANOVNA project .
