VEGAPULS C21 is a non-contact radar level sensor for measuring the level of liquids and bulk solids. It is particularly suitable for water and wastewater applications, pumping stations, stormwater overflow basins, open-channel flow measurement and general level monitoring. The sensor offers a measuring range of up to 5 m, an accuracy of ±2 mm, a 4–20 mA/HART output and can be configured via the VEGA Tools mobile app. It is also suitable for use in hazardous areas. The sensor can be connected to any data logger that supports the corresponding analogue/HART input.
Description

VEGAPULS C21 – Non-contact radar level sensor

VEGAPULS C21 is a compact radar sensor for non-contact level measurement in applications where a high degree of protection and reliable operation under demanding conditions are required.

The sensor is particularly suitable for:

  • water and wastewater treatment plants;

  • pumping stations;

  • stormwater overflow basins;

  • level monitoring in sewer and water utility applications;

  • flow calculation in open channels;

  • small bulk material silos and open containers.

Radar technology provides non-contact measurement, which means the sensor does not need to come into direct contact with the measured medium. This reduces maintenance requirements and makes it suitable for applications where traditional submersible sensors may be difficult to use.
