For high-temperature, high-viscosity liquids, what device is used to determine whether they have been completely removed from the pipes?

I would like to ask: for a vertically downward pipe containing a fluid at 160°C and with a viscosity of 10,000 cp (according to available information, the viscosity of materials in the polymerization reactor is 110 CP, while that in the initiation reactor is 800,000 CP), what type of instrument should be used to determine when the liquid in the pipe has been completely emptied? Tuning fork level switch/RF admittance level switch/Ultrasonic level switch Rotary obstruction level switch-Ray level switch Float switch – Dear colleagues, please share your ideas on the most suitable solution! The viscosity of 110CP is basically the same as that of 20# automotive engine oil
“10000cp”？ It’s too sticky to dig. . . Is there paper glue available? ,,Is there any honey sticking around? Is there any syrup sticking to the sugar-coated haws? . . I have no idea how sticky it is; bro, I’m just here to chat casually. . .
It seems there is no instrument that can indicate whether the pipeline has been emptied; substances with high viscosity will definitely stick to the walls to some extent. For safety reasons, if the pipeline isn’t very long, steam can be used to clean it
Similar to syrup? ………… Wow, 1W CP… I have the feeling that there’s no driving force behind it; with only gravity at play, the medium basically can’t move through the pipe……
The viscosity of 10,000 cp is “almost like syrup” – great information, thanks to the original poster! I’ve learned something new, thank you to the original poster! I’ve learned something new, thank you to the original poster! What is the pressure in this “vertically downward pipe”? ,, What is its inner diameter?
It is purged with nitrogen and must not come into contact with water or air.
For 80WCP, does it become a solid?
It has high viscosity, so the ray switch is still quite reliable
The voltage rating of the rotary switch is insufficient
High-viscosity tuning forks also tend to stick easily
RF admittance will have many false alarms
