Radar Level Measurement for Carbon Black Silo to Prevent Raw Material Loss

Introduction

Carbon black is a fine powder material widely used in rubber, battery, and chemical industries.

However, accurate level measurement in carbon black storage tanks or silos is difficult due to its low bulk density, high conductivity, and dusty environment.

Conventional point level sensors such as vibrating level switches may fail to detect the material properly, which can lead to overflow, raw material loss, or unexpected process shutdowns.

In such applications, radar level transmitters provide reliable non-contact measurement, enabling stable continuous monitoring even in dusty conditions.

There is a risk that the existing upper limit level sensor (Vibrating Level Switch) may not detect because the density of high conductivity carbon black is quite low and light.

Stable continuous level measurement is required to reduce the risk of raw material loss or unwanted operation shutdown due to overflow.

Solution

Radar Level Transmitter is a superior measuring instrument for measuring various solid or liquid material in tank, silo, hopper, etc.

It uses principle of electromagnetic-wave and it is less-influence from suspended dust or gas in the process, therefore, possible to provide stable level measurement under the process.

Furthermore, maintenance is simple and easy because there is no mechanical moving parts and consumable parts.

Finally, the risk of overflow and raw material loss is solved by the radar level transmitter.
