Introduction
In modern chemical processing facilities, maintaining precise liquid level measurements in storage tanks is crucial for safety, operational efficiency, and regulatory compliance. Many chemical processes involve high-temperature liquids that generate significant steam, creating challenging measurement conditions. Additionally, condensation can form on sensor surfaces due to temperature differentials within the tank, further complicating accurate measurement.
Traditional level measurement devices, including float switches and ultrasonic sensors, often struggle under these conditions. Signal distortion, refraction, or scattering caused by steam and condensation can lead to inaccurate readings, triggering unnecessary alarms, production interruptions, or even safety risks.
Linpowave’s millimeter-wave radar technology is specifically engineered to overcome these challenges, delivering precise, reliable, and non-contact measurements in harsh industrial environments. By leveraging high-frequency radar waves, advanced signal processing, and intelligent algorithms, Linpowave provides a robust solution for chemical tank applications.
Challenges in Steam and Condensation Environments
Steam Interference
High-temperature chemicals in storage tanks produce vapor above the liquid surface. This steam layer has a refractive index different from air, causing radar waves to bend or scatter as they propagate. As a result, conventional sensors can misinterpret the liquid surface position, resulting in inaccurate measurements.
For example, ultrasonic sensors can be absorbed or deflected by steam, while optical sensors may experience signal attenuation or inconsistent reflections. Even minor inaccuracies can lead to process inefficiencies, overfilling risks, or wasted product.
Condensation Effects
Condensation occurs when humid vapor meets cooler surfaces within the tank or on the sensor itself. These liquid droplets can alter the electromagnetic properties of the measurement path, creating additional reflections or signal absorption. Non-contact sensors can partially mitigate this effect, but careful design and signal processing are required to ensure stability.
Combined, steam and condensation create a dynamic and unpredictable measurement environment, demanding a solution capable of maintaining accuracy under varying conditions.
