Under what circumstances should a radiation source level gauge be used?

Radar level gauges use electromagnetic waves, while ray source level gauges employ sources such as cobalt 60 or cesium 237; the latter is more commonly used, but the former has greater penetration power. The ray level gauge is the ‘last resort’ for level measurement, as it is not easily used due to the presence of a radiation source. If a company has just one of these, it’s like keeping a gun illegally; applications, maintenance, and disposal all require involvement from official authorities. Based on personal experience, the following conditions need to be met simultaneously for it to be possible to use rays: 1. The key liquid level considered in the process, or the shutdown liquid level. 2. It’s basically a slurry that solidifies as soon as it’s produced, making it impossible to transmit pressure. 3. When the temperature is high enough to be outside the range of the radar, for example above 200 degrees, the capillary cannot remain stable for long. 4. The pressure is high, which makes backblowing difficult as well. I haven’t chosen to use radiation myself; I have designed systems, but it was always the requirements of the patent holders – for example, in PTA plants, as we all know, radiation is used, and in significant amounts. @jiaguoyun

Ray level gauges are primarily used for measuring the level of solid particles or powdered materials. For levels that can be measured by other methods, ray level gauges are generally not utilized. The management, maintenance, and repair of radiation sources are quite complicated, and such devices also require regular inspections by **relevant authorities.

It is generally used on large tanks and reactors, where the medium stored or reacted is in the form of a slurry or similar.

We have used it for measuring solid material levels at high temperatures, in a switch-like function. During use, it was found that the lining bricks in the high-temperature silo expanded and contracted due to temperature changes, causing the transmitting and receiving ends to shift out of alignment, which rendered it unusable. Personally, I think it’s better to avoid using instruments that rely on radiation sources. If it’s imported equipment, one must be even more cautious; such devices are given special attention during customs clearance. Moreover, obtaining various approvals from the National Security Bureau and regulatory agencies before installing and using them is quite troublesome. Strict regulation is understandable in this case. In the future, you’ll also need to have professional institutions conduct regular checks for environmental leaks, and the equipment should be protected with iron doors and fences. If it were stolen by scrap collectors, it could cause a huge uproar throughout the city. So if it’s possible to avoid using it, definitely don’t use it.

Ray source level gauges are primarily used to measure the level of materials that are high-temperature, high-pressure, highly viscous, corrosive, boiling, or toxic (in solid or liquid form) within sealed containers.

Radioactive level gauges are generally used to detect the level of solid particles, such as the catalyst level in a reactor. Relative risk, trouble. Radar has many applications; I think that as long as you want to, it can be used for detection in normal operating conditions.

I know that in the steel industry, radiation sources are used for measurement on slabs or billets; I’ve forgotten whether it’s cesium-237 or cesium-137. Purchasing, installation, transportation, dismantling, and storage all require numerous approvals. I think it’s mainly used in high-temperature environments (where other level detection methods such as ultrasound and radar are not suitable)
