Level meter

Today, let’s learn about the characteristics of the working conditions of polyolefin plant sump and see what kind of radar level meter is more applicable under such working conditions. I once read some information about a coal chemical company. The information recorded that a coal chemical polyolefin plant had a total of four cesspools. The […]

In fact, guided wave radar level meters also have a very wide range of advantages. In certain special conditions, the performance of a guided wave radar level meter far exceeds that of a non-contact radar level meter. Therefore, it is essential to explore the advantages of guided wave radar level meters, which may help some

Many people always think of radar level meters as a contactless measurement method. In fact, in addition to the contactless measurement method, there are also contact-guided wave radar level meters. On the market, although the guided wave radar level meter does not hold obvious advantages, because of its low price, the scope of application is

The ultrasonic waves emitted by an ultrasonic level meter are mechanical waves that cannot be propagated in a vacuum and can only be propagated through a certain medium. Radar level meters, on the other hand, are the opposite. The microwaves emitted by radar level meters, which belong to electromagnetic waves, do not need a medium

The radar level meter has undergone numerous tests during the development process and the accuracy has been based on numerous experiments. However, the actual working conditions are not equal to the test working conditions. The actual working conditions may include heating devices, a limit switch in the storage tank, etc. These can cause interference to

The chemical industry is one of the more complex of the many industries. It is complex mainly because of the environment and the complexity of the production process, which may undergo one or more chemical reactions, or perhaps more than one physical reaction. Therefore, the chemical industry is very careful when choosing instruments and meters.

Before the advent of electronics, the main level detection methods were based on mechanical mechanics. The development of microelectronics has greatly facilitated the development of sensing technology and as a result, many new level detection methods and instruments have been created. Among these instruments, the radar level meter is based on the time travel method.

Radar level meters emit microwaves, which are electromagnetic waves. The reflectivity of the electromagnetic wave signal is influenced by the size of the dielectric constant of the liquid being measured. When the radar waves emitted by the radar level meter reach the surface of the liquid medium, refraction and reflection will occur. The greater the

The accuracy of the radar level meter depends on whether the selection is correct, the installation is accurate, and the installation position is appropriate, but more often than not, it also depends on the quality of the return wave. The better the quality of the echo, the more accurate the measurement, and conversely, the more

Ultrasonic level meters and radar level meters have both been developed based on the time travel method. There are many similarities between these two types of level meters, but the differences between the two are also obvious. The biggest disadvantage of ultrasonic level meters is that they are not suitable for measurements at high temperatures
