The VEGAPULS 21 is a compact, non-contact radar level sensor designed for continuous level measurement in water tanks, chemical containers, and utility systems. With 80 GHz radar technology, it offers reliable, maintenance-free performance in standard marine and industrial applications.
The VEGAPULS 21 is a modern radar-based level sensor built for continuous, non-contact measurement of liquids and bulk solids. Its 80 GHz radar signal provides narrow beam focusing and high sensitivity, making it ideal for installation in small tanks and confined spaces — even when internal structures, foam, or vapor are present.
In the maritime industry, the VEGAPULS 21 is well-suited for monitoring water tanks, additive containers, and technical service vessels. It is also a preferred choice for applications involving plastic or non-metallic tanks, as it can measure through tank walls without requiring process penetration.
The sensor features a sealed plastic housing with IP66/IP67 protection, ensuring resistance to spray water, cleaning agents, and salt-laden environments. Its non-contact measuring principle means there are no moving parts, reducing wear and eliminating the need for recalibration — a key advantage in remote or hard-to-access locations.
Marine Technic supplies the VEGAPULS 21 to shipbuilders, fleet operators, and engineers seeking a compact and affordable radar sensor solution. As a specialist in VEGA instrumentation, Marine Technic delivers sensor technology that meets the reliability standards expected in marine and offshore systems.
