Issue with liquid level measurement in the sulfur recovery liquid sulfur tank
Thread Content
Previously, in our facility’s sulfur recovery unit, double-flange level gauges were used to measure the level of liquid sulfur. However, the diaphragms of these level gauges often got damaged, and the heating system associated with the root valves was inadequate, which led to frequent problems caused by crystallization and blockages. I would like to ask everyone: does anyone have a better method for measuring the liquid sulfur level under such operating conditions?
Back-pulse level gauges and radar level gauges are highly stable.
Ordinary radar + blowing air can be used very effectively
Hello, could you provide a detailed introduction?
Hello, what is the principle behind a backflow level gauge? Could you provide a detailed explanation?
The back-blow level gauge operates on the principle of a constant critical compression ratio; a stainless steel tube is inserted from the top of the tank to the bottom, and a certain flow rate of nitrogen is blown in using a rotameter. A tee connects the tube for blowing in gas, the tube extending to the bottom of the tank, and the differential pressure transmitter or pressure transmitter – you can find more information by searching on Baidu. We have been using these two types of level gauges here for 10 years.
Okay, I see. It’s a blowing-type measurement
A friend recommended radio frequency admittance; it should also be a very good solution.
Radar is the most cost-effective, accurate, and maintenance-free liquid sulfur measurement instrument. Magnetic flap valves work too, but they need to be modified by oneself to function properly.
