Crude oil, customarily called untreated petroleum, consists mainly of elements or compounds such as carbon, hydrogen, sulfur, nitrogen, oxygen, and metals. It was first discovered and applied by our country. With the progress and development of society, many countries have included it as an important national resource and use radar level meters to measure and monitor its level.
However, in the process of measuring and monitoring crude oil, a number of problems have arisen, which are discussed below.
Problem 1: Within the zone, the measured value of the radar level meter appears to jump.
Radar level meter measurement value in the area of the jump, most by three reasons, namely the measured liquid interface instability; tank walls appear hanging oil; near the antenna there are adhesions. These three situations can cause measurement fluctuations.
Problem 2: The radar level meter has a lost wave.
In reality, the frequency of this situation is not very high, but it does happen occasionally, so it is necessary to recognize it. The reason for this is that most of them are not installed or maintained in place.
For example, the radar level meter antenna is not kept perpendicular to the measured liquid interface, which can lead to loss of wave; the antenna has not been cleaned for a long time, resulting in condensation or excessive adhesion, which can also cause loss of wave.
These are the two most common causes. In addition, if there is too much foam at the interface of the liquid being measured and the interference is too heavy, this can also lead to a loss of wave, and it is then necessary to change to a more suitable type of level meter.
Problem 3: No change in the measured value of the radar level meter
The most common reason for this to occur is that a fixed emitting surface appears within the radar level meter beam range and excessive interference causes the measured value to remain unchanged. In addition, the failure of the electronic module can also cause such problems.
Such problems can occur when radar level meters measure crude oil. In fact, similar problems can occur when measuring other media with radar-level meters. Therefore, we need to learn how to solve these problems, so that no matter what kind of conditions we encounter and what kind of measurement media, we can quickly find the cause of the problem and find a solution.
