VEGA VEGAPULS C 21 Radar Level Sensor

Product Overview

Wired Radar Level Sensor

VEGAPULS C 21

VEGAPULS C 21 is a radar level sensor manufactured by VEGA that provides non-contact level measurement of liquids and bulk solids in simple applications where a high degree of protection is required. It is particularly suitable for use in water treatment, pumping stations, rain overflow basins and level monitoring.

The VEGAPULS C 21 is a maintenance-free operation due to non-contact 80 GHz radar technology and is able to give exact measurement results independent of medium properties, process and environmental conditions.

A low cost sensor with an axial cable outlet, 4 … 20 mA/HART output, measuring range of up to 15m and a plastic housing (IP66/IP67) making the radar sensor suitable for simple measuring tasks.

Technical Specification

Level measurement at the water source

VEGAPULS C 21 provides non-contact continuous level measurement with radar at the water source. Spring water originates from surface water, which passes down through layers of porous rock on its way down into the earth. It then flows horizontally along a layer of clay or rock and thus forms a spring. To obtain drinking water, the spring is impounded in some type of structure and protected against contamination. The spring water flows into a settling pond and then into a reservoir. A reliable level measurement is critical in ensuring a sufficient supply of drinking water.

Water level gauging in the cooling water intake structure

VEGAPULS C 21 non-contact water level measurement with radar in the inlet shaft. Coal fired power stations use huge amounts of cooling water. This water is usually taken from rivers, with the help of specially built intake structures. At these extraction points, reliable level measurement in all weathers and surface conditions is needed to ensure an ample supply of cooling water for the operation of the plant.
