For continuous level measurement of solid materials
The small-sized process connection is particularly advantageous in small containers and narrow spaces. The instrument has strong signal focusing capability and can be used in large silos or containers with various internal components.
High Equipment Availability due to Wear Resistance and Maintenance-Free Operation
Thanks to 80 GHz high-frequency radar, the VEGAPULS 69 radar level gauge can measure all solid materials: fine powders, ash, dried sludge particles, waste glass fragments, various granules, or coarse solids—without being disturbed by dust. The instrument has a large measurement range and high accuracy, enabling reliable measurement in both large and small applications, such as various material sheds, containers, and silos. In addition, measurement results are not affected by internal components. Whether measuring aggregates, sand, cement, and other building materials, or being used in chemical industry, sewage treatment, waste recycling, etc., non-contact radar level gauges are ideal solutions.
In non-contact level measurement using radar, the level gauge emits microwave signals from above to the medium, and the surface of the medium reflects them back. Based on the received signals, the level gauge can measure the distance to the medium and thereby calculate the accurate level.

Level Gauges for Continuous Level Measurement
Typical applications of continuous level measurement include reaction kettles, storage tanks, or silos in the process industry.
Non-contact radar level gauge: The instrument emits high-frequency microwave signals, which propagate through space from the antenna. When encountering the material surface, part of the signals is reflected back and received by the antenna. The instrument calculates the distance between the material surface and itself by measuring the time difference or frequency difference between the transmitted and received signals, and then derives the material level height.
Guided wave radar level gauge: Radar pulses are transmitted along a cable or rod-shaped measuring probe, reflected at the medium surface, and returned to the level gauge along the probe. The built-in electronic components calculate the distance by measuring the propagation time of the pulses, thereby obtaining the level height.
Precise measurement: Unaffected by steam, dust, noise, and material properties, it can provide accurate level measurement results under complex working conditions. For example, VEGAPULS 69 can stably and accurately measure in wood chip silos with dust and steam and strong adhesion.
Wide application range: Capable of measuring various solid media, including fine powders, ash, dried sludge particles, waste glass fragments, various granules, or coarse solids. It can also be used in different types of storage equipment such as tall silos, large material sheds, and containers with partitions.
Maintenance-free: Adopts non-contact measurement, with no wear issues, requiring no maintenance during operation, thus improving equipment utilization.
Easy installation: Non-contact radar level gauges are usually installed on the top of containers without the need to enter the container interior, making installation simple; guided wave radar level gauges only require inserting the measuring probe into the container during installation.
Strong signal processing capability: Equipped with powerful signal processing functions, it can effectively identify and process real echo signals, suppress false echoes and interference signals. For example, VEGAPULS 69 can effectively avoid false signals generated by the inclined wall of the silo bottom cone by adjusting the universal joint angle and utilizing its high focusing and small emission angle characteristics.
Main Models and Applications of VEGA Radar Level Gauges
VEGAPULS 69: An all-round 80 GHz radar instrument with strong signal focusing capability. It can be equipped with a sealed plastic antenna or a built-in lens antenna with a metal flange, suitable for tall silos, large material sheds, and containers with partitions. It can measure all solid media and performs excellently in level measurement of wood chip silos in paper mills, for example.
