Fluctuations in the liquid level gauge
Thread Content
This is an acetic acid level gauge that is preheated using a steam coil. After preheating, when steam is introduced, the level of the liquid in the gauge drops gradually to a very low level (for example, it drops from 3 meters to less than 1 meter). When the steam supply is stopped, the liquid level rises back up to over 3 meters. Could it be that the temperature of the preheating steam is too high? I hope experts can give me some advice
It depends first on the working principle and installation method of your level gauge to conduct an analysis...
For preheating with steam, it should be a magnetic flap valve, right? If it’s a magnetic flap type, could it be that the high temperature resulting from the introduction of steam affects the density of acetic acid, causing its density to decrease and the float to drop?
It seems that the pressure inlet at the top of the level gauge is blocked.
What kind of level gauge is it? I need to know the measurement principle in order to help you analyze it.
Yes, there are various types of level gauges, such as external-mounted level gauges and so on.
You should explain in detail what type of level gauge it is! Only in this way can the right solution be found
If the temperature is too high, the medium vaporizes, and the rising air flow causes fluctuations.
It is a magnetic flap level gauge, 5 meters long for the tank area
