How To Choose A Radar Level Sensor Suitable For Autoclave?

Whether it is nickel production or zinc production, an advanced technology - hydrometallurgy technology is widely used. In this process, the autoclave is the core equipment, and the autoclave level measurement is one of the most important parameters. So the question is: Can the radar liquid level sensor be used when measuring the liquid medium in the autoclave?

To figure out this problem, we first need to understand the working conditions in the autoclave. Generally speaking, the liquid medium in the autoclave is usually ore slurry, and it has a certain corrosiveness. In addition, the autoclave is often in a state of high temperature and high pressure during operation. How high it is depends on the specific working conditions. Steam may be generated, and most autoclaves are also equipped with stirring devices.

From these working conditions, the autoclave high temperature radar is fully capable of measuring the liquid level in the autoclave. High-frequency radar level gauges are almost unaffected by corrosion, water vapor, high temperature and high pressure. However, when choosing a suitable radar liquid level sensor, you need to pay attention to the following points:

1. When choosing an autoclave high temperature radar level gauge, the key is to consider the material of certain components. Since the liquid in the autoclave is corrosive, the antenna and some components of the radar level meter should be made of corrosion-resistant materials, such as PTFE.

2. Since the temperature in the autoclave may be as high as about 150°C, a radar liquid level sensor model suitable for high temperature environment should be selected. Generally speaking, radar level meters are available in standard and high temperature types. The working temperature of the standard type is about 130°C, while the high temperature type can reach about 250°C.

3. Compared with guided wave radar level meters, non-contact autoclave high temperature radar level meters are more suitable for measuring liquid media in autoclaves. Non-contact radar level meters usually adopt an integrated design, which is easy to install, pollution-free and wear-free.

In theory, autoclave high temperature radar level meters can be fully applied to the measurement of liquid media in autoclaves. However, the specific model to be selected and how to install it correctly need to be reasonably selected by technicians according to the specific working conditions, and appropriate cooling and pressure reduction measures should be taken when necessary.
