product overview

LB 440-M is a non-contact liquid level measurement device developed by BERTHOLD company, specifically designed for industrial process monitoring. This product adopts gamma radiation technology and can measure the liquid level of liquids, powders, and granular materials in real time through container walls (such as metal, plastic, glass). It is suitable for tank monitoring in chemical, food, pharmaceutical and other fields.

Main features and advantages

Non invasive measurement: does not require contact with the medium, avoiding contamination or damage to the container structure.

High precision and stability: Based on the principle of gamma ray attenuation, the measurement error is low and the long-term operation reliability is strong.

Multi scenario adaptability: compatible with liquids, powders, and particles, supporting various container materials such as metal, plastic, glass, etc.

Modular design: can be extended to multiphase liquid level monitoring systems (such as EmulsionENS), suitable for density curve analysis of complex layered materials.
