The unit is currently in the water commissioning phase, and a liquid level is being established in the storage tank (methanol is used as the medium during normal operation). The magnetic flap gauge shows 80%, while the radar gauge shows only 58% – why is that? Could it be due to inconsistent dielectric constants? Solve······:call:
Radar is inaccurate; π_π radar is the most suitable for situations where the medium is stable, as gas phases have a significant impact in storage tanks containing alkanes.
The dielectric constant of the radar can cause measurement errors, so it can be corrected after feeding begins.
The medium is different; water has a higher density, so its actual height is lower than that of methanol with the same volume.
I have consulted the manufacturer, and the response was that the density of the medium has little impact during radar measurement.
It has nothing to do with density; the spacing between the flanges on which the magnetic flip plate is installed and the length of the radar cable are both factors that cause discrepancies in the readings
It is necessary to consider whether the zero points of the magnetic flip switch and the radar are at the same height; when displaying percentages, the full-scale setting also needs to be taken into account. The conditions in different sites vary, and the radar configuration parameters as well as whether the configuration is correct must also be considered. In short, it’s just a minor issue
You need to analyze this on your own first – find out approximately what the liquid level is. If it’s a sealed device, the presence of water vapor can affect the radar’s transmitting and receiving functions
First, you need to ensure that the level of your liquid in the tank is proper before addressing any issues with the radar. Changes in the density of the medium in the tank, fluctuations in liquid level, weather conditions, and the installation location can all have an impact. Additionally, the parameters of the radar itself – such as its resistance to interference, filtering capabilities, and the choice of wave strength – also play a role. It’s not possible to generalize; each factor needs to be checked individually
