Accuracy of radar level meter
In recent years, the application range of radar level meter is more and more wide, and has been favored by the majority of customers and friends. So, does this mean that the measurement accuracy of China’s radar level meter has also reached the international technical level?
In fact, with the current status of production technology in China and the degree of development of China’s instrumentation industry, there are still some gaps with the international level. Because of this, it is necessary to deepen the awareness of radar level meters, and find gaps on the basis of real understanding of products to further innovate and improve.
Therefore, the expert introduced that the measurement accuracy of the radar level meter, the radar level meter measurement range is calculated from the point where the beam touches the tank low, but in special cases, if the bottom of the tank is concave or cone, when the level is lower than this point can not be measured. In addition, if the medium is low dielectric constant, the bottom of the tank will be visible when it is at a low liquid level. In order to ensure the measurement accuracy, it is recommended to set the zero point at a low height of C.
In theory, it is possible to measure the position of the antenna tip, but considering the effects of corrosion and adhesion, the final value of the measurement range should be at least 100mm from the antenna tip. After clearing the measurement of the radar level meter, let’s take a look at the requirements for the installation of the radar level meter:
1. Recommended distance (1) from the wall to the outer wall where the short pipe is installed.
2. The minimum distance from the tank wall is 1/6 of the diameter of the tank. The minimum distance is 200mm.
3. It cannot be installed above the feeding port (4).
4. If the distance between the instrument and the tank wall cannot be maintained, the medium on the tank wall will adhere to cause false echoes, and false echoes should be stored when debugging the instrument.
The accuracy of the radar level gauge the absolute amount of the general standard error:
Measurement level: 0.5mm, 1mm (the radar of this grade is obviously higher in various parameters)
Monitoring level: 3mm,
Process level: 5mm, 10mm.
High-precision radar, to use communication methods to fully retain accuracy, because the current signal accuracy to 1/1000 is good, such as 10m range, 1/1000 is 1cm, less than 1cm accuracy is submerged in the signal.
