With the continuous improvement of industrial automation, the demand for accurate measurement of liquid media is growing. Especially in the chemical, pharmaceutical, food and beverage industries, the monitoring of low-viscosity liquid media is particularly critical.
As a non-contact liquid level measurement technology, radar level meter plays an important role in the measurement of low-viscosity liquids due to its advantages of high precision, good stability and wide adaptability.
Low-viscosity liquids usually refer to fluids with low dynamic viscosity, which have strong fluidity and are easy to transport and mix. Such media, such as water, alcohol, and certain oils, exhibit good flow properties at normal temperature and pressure.
However, low-viscosity liquids also bring some challenges when measuring the liquid level, such as easy to generate fluctuations, foam, and steam, which may affect the accuracy of the measurement.
Therefore, it is crucial to choose the right measurement technology. Radar level meters measure the liquid level by emitting microwave signals to the surface of the measured medium and receiving the reflected signals.
Since radar waves are not affected by changes in the color, density, and temperature of the medium and do not come into direct contact with the medium, they are very suitable for continuous measurement of low-viscosity liquids.
A chemical plant needs to monitor the liquid level of a large tank storing low-viscosity solvents in real time. Considering the volatility of the solvent and the changes in environmental conditions, traditional float or pressure level gauges are difficult to meet the accuracy requirements.
Therefore, a high-frequency radar level gauge was selected for installation. During the implementation process, the technicians first determined the installation position of the radar level gauge to ensure that the microwave signal can irradiate the liquid surface vertically and avoid interference from surrounding structures.
By adjusting the radar parameters, the measurement performance for solvents, a medium with low dielectric constant, was optimized.
In actual operation, the radar level gauge showed extremely high stability and repeatability, and could accurately measure even when there were slight fluctuations in the tank.
Radar level meter plays an indispensable role in the measurement of low-viscosity liquid media. Its non-contact measurement method, high adaptability and excellent measurement performance make it the preferred level measurement tool in current and future industrial automation and process control.
As industry needs continue to deepen, the technology of radar level meter will continue to innovate to meet more diverse and precise measurement needs.
