Measure level in a 2 Litre Lab flow Reactor operating in CSTR mode; under pressure.
(OP)
We have a 2 Litre Lab reactor we wanted to convert to a CSTR trial. The reaction involved is Liquid Liquid and takes place at approx 130 C with 6 bars autogenous pressure. The reactor has in internal coil and a Rushton type stirrer magnetically coupled.
Two liquids are co-dosed by dosing pumps through top nozzles and the liquid is continuously withdrawn as well through a bottom nozzle.
What options do I have to maintain the level inside the reactor? Any ideas? Has anyone used a setup like this before?
Capacitive? dP gauge? Radar? What can work on a small sized reactor like this.
I am drawing a lot of dead ends looking this up.

Good idea. I hadn't thought of it. But I suppose that gets tricky because I have two liquids of different density? And then the density varies with Temperature. Though to be fair I don't need to be super accurate about levels. It's only a functional thing to keep the reactor ops stable.
Another problem would be bubbling / frothing etc?

There are devices for aquariums that will top off the tank as the water level changes (e.g. https://www.amazon.com/Hydor-Smart-Level-Controlle...).
There are also ultrasonic drum level gauges (battery powered usually), you may have to call a vendor (e.g. Cole-Palmer) to see if they have something small enough for a 2L lab scale reactor nozzle.

Try it out with water or solvent if you can't tolerate getting your stuff wet.
Goodluck.
