Liquid oxygen is a commonly used industrial oxidizer with a wide range of applications in aviation, aerospace, nuclear energy and other fields.

The storage of liquid oxygen requires the use of liquid oxygen storage tanks, and liquid oxygen storage tank level measurement is an important issue. So, can radar level meter measure the level of liquid oxygen in liquid oxygen storage tank? This paper will introduce the measurement difficulties of liquid oxygen storage tanks and provide two actual measurement cases to show the application of radar level meter in liquid oxygen storage tanks.

Liquid oxygen storage tanks have some special problems in level measurement: Low temperature: the storage temperature of liquid oxygen tanks is very low, generally below -182°C, which poses a great challenge to traditional level measurement equipment. Liquid oxygen is a flammable liquid: liquid oxygen is a flammable liquid, which means that ignition sources and other factors that may cause safety accidents should be avoided in level measurement. Liquid oxygen is toxic: Liquid oxygen is a toxic liquid, which means that it is important to prevent harm to the operator during level measurement.

Let's look at two actual measurement cases to understand the application of customized radar level meter in liquid oxygen storage tanks. Case 1: Liquid Oxygen Plant A large liquid oxygen plant in Asia uses a set of liquid oxygen tanks for storing liquid oxygen, which is difficult to measure the level. The original level measurement instruments were difficult to work in the very low temperature environment. For this reason, the plant utilized radar level meters for level measurement. The radar level meter uses advanced microwave signal technology, which is able to penetrate the pressure shell of the liquid oxygen tank and can accurately measure the liquid level height. The instrument is explosion-proof, low-temperature, highly anti-interference, stable and reliable, and can accurately read the liquid level height and changes in a strongly interfering environment, which greatly improves the plant's manufacturing efficiency and output quality. Case 2: Airline Repair Station An airline repair station located in North America stores a large amount of liquid oxygen that requires level measurement. Their liquid oxygen storage tanks lacked proper level measurement equipment, so they contacted a china radar level meter factory. Radar Level Meter provided them with a solution for liquid level measurement. Radar level meters use high frequency microwave signals transmitted in liquid oxygen to penetrate tanks under high pressure to accurately and consistently measure liquid level height. At the same time, the radar level meter can also maintain good linearity and accuracy, and can work normally under extreme temperature and pressure, which can adapt to the special nature of liquid oxygen and provide reliable level data.

Radar level meter has significant advantages in liquid oxygen storage tank level measurement. Liquid oxygen storage tanks have greater difficulty in level monitoring, such as low temperature, flammable, toxic and many other factors, but radar level meter can cope with these challenges, provide accurate, stable and reliable level measurement data, help users to improve production efficiency and product quality.
