Selection and design issues for high-pressure vessel level gauges
Thread Content
The pressure is 12–13 MPa, the temperature is 260–290°C; the medium is a turbid liquid. The height of the container is 300 mm, and the liquid level is around 240 mm. Is it possible to use a level gauge under such conditions? If so, please recommend one
““Container height 300mm”? Really? Really? What material is being measured? Do materials have a volatilization and solidification effect? If you can answer the questions well, come to me for the tough ones. . . A liquid level of 300mm is high enough; I’ve also measured levels of 30mm, and they’re quite substantial as well. .
Well, yes – the liquid level is roughly 20 centimeters in total height, and there is also stirring; it’s a type of system with a variable liquid level
The material is composed of alcohols and solid substances, and it has no solidification effect
1. “Alcohols”: Are they volatile? Will it form a liquid phase when exposed to cold? This needs to be made clear. 2. What is the diameter of the tank? What is the gap between the tank wall and the stirring blades? These two points also need to be made clear
Low volatility, does not solidify, diameter 25 cm, gap between tank lid and stirring blade is 5 cm
““Diameter 25 cm”, “Height 300 mm”. Ugh,,,,:lol. Well, considering the wall thickness as well as devices like the heating coil, this container is basically a large pot – like a big-sized pressure cooker, right? This little thing – I guess it’s not worth using an expensive high-temperature differential pressure gauge with a diaphragm that doesn’t come into contact with liquid, just to measure its liquid level I guess by placing the pot on a gravity sensor, and using that sensor as a support point for the pot, it would be easy to determine the liquid level. My brother can also manufacture this type of gauge; it’s generally used for measuring levels in powder tanks, and not typically for measuring liquid levels. Here’s a picture of it.
