How to choose a high-temperature and high-pressure level gauge?

I think radioactive level gauges are the best; I’ve used them and they work well. They are easy to calibrate, and no drilling is required on the equipment, making them an excellent choice for measuring in high-temperature, high-pressure, sealed containers. The only downside is that the procedures involved to get them installed can be complicated.

The FY2B series of intelligent high-temperature and high-pressure capacitive level gauges utilize the latest microcontroller processing technology; they are specialized measuring instruments designed specifically for detecting the levels of high-pressure liquids that are difficult to measure, such as those in cold exchangers, ammonia separation units, and alcohol separation units within the synthetic ammonia industry! The maximum voltage resistance is 32 MPa, and the maximum temperature resistance is around 250°C! Another type is the intelligent boiler drum level gauge, which is also of the capacitive type; it is generally used in boilers, with a maximum pressure tolerance of 16 MPa and a temperature tolerance of around 500°C!

Well, a high-pressure capacitive level gauge could be considered; it offers high precision and good stability

Reserve a seat,,, Let me think about it first, I’ll update the post later~~~~~~~~~~~~~~~~~~~~~~~~~~~·

A pressure of 100 bar is quite high. Given the high temperatures, I recommend using a radiation-level gauge, but be extremely careful when using it. Today I went to the site to write down the numbers of various radiation sources, and it was inevitable that I would come into close contact with the lead shields surrounding those sources. But later on, I kept feeling a bit dizzy. :(

Thank you all for your advice. Regarding radiation source level gauges, I don’t think they are very safe; their price is certainly high, and there are also many procedures to follow, which is too much hassle； Regarding capacitive level gauges, the temperature should meet the requirements. As for pressure, I think it’s a bit high. Moreover, since the media being measured are different, could that have any impact on the performance? As for radar level gauges, what is their pressure resistance rating? Can they withstand 100 bar?

Given the operating environment you mentioned, a radiation level gauge is necessary; nothing else will work reliably……

3051 Remote-transmission flange-type pressure level gauge. Suitable for applications involving corrosion, high temperatures, viscous fluids, crystallizing substances, and high hygiene requirements; as well as viscous fluids at high temperatures, substances that tend to crystallize, fluids containing solid particles or suspended matter, and highly corrosive or highly toxic substances. It helps to prevent leaks in the pressure transfer tubes from contaminating the surrounding environment； It eliminates the tedious task of frequently replenishing the isolation fluid, which is necessary when using an isolation fluid due to the instability of the measurement signal. Continuous and accurate measurement of the interface and density, along with remote transmission capabilities, prevents mixing of the media at different moments, thereby ensuring that the measurement results accurately reflect the actual changes in the process. In environments with high hygiene requirements, such as in the food, beverage, and pharmaceutical industries, it is necessary not only for the parts of the transmitter that come into contact with the medium to meet hygiene standards, but also for them to be easy to clean in order to prevent cross-contamination between different batches of medium.

Many types of level gauges can be used, such as electric float level gauges, magnetic flap level gauges, and so on

OP, based on the conditions listed, they aren’t particularly stringent; with 100 Bar pressure and a medium of diesel or wax oil, it should be used in the high-temperature section of diesel or wax oil hydrogenation units. A differential pressure level gauge combined with a magnetic flap level gauge could be considered, but the magnetic flap level gauge needs to be imported, and spare parts must be kept on hand as they tend to break easily. This combination should be quite reasonable. Of course, if the medium becomes heavier, such as residue oil, differential pressure level gauges are no longer reliable. I’m facing this problem right now. Additionally, for radioisotope level gauges, it’s necessary to take into account the thickness of the container walls; if they are too thick, the measurements become inaccurate. I’ve tried this already ； 2. Guided wave radar may be affected by both temperature and wall thickness.
