UWT Radar Level measurement at the speed of light

Learn more about our radar level transmitters to reliably measure solid and liquid materials in silos and tanks.
We have solutions for the most diverse industries. Our radar sensors include a non-contact series NivoRadar® 3000 and a guided wave radar serie NivoGuide®3000 for solis and NivoGuide® 8000 for liquids.

Electromagnetic waves form the basis of level measurement with radar. A radar sensor emits a focussed electromagnetic wave that is reflected by objects as an echo and is then evaluated by the sensor. In addition to free-radiating radar sensors, the radar category also includes those based on guided microwave technology, which are referred to as guided radar, TDR (time domain reflectometry) or also GWR (guided wave radar) sensors.

The fundamental difference between free-radiating and guided radar sensors is the way the electromagnetic waves reach the medium to be measured. While free-radiating radar sensors use special types of antennas to transmit the waves in the direction of the material without contact, guided radar sensors require a probe (rod or cable) as a waveguide along which the signal is guided to the medium. The probe is in contact with the medium.

Free-radiating radar sensors are generally characterized by their frequency, since this is important for non-contact level determination in process or storage vessels. Radar sensors with high frequencies can be built more compactly, have smaller radiation angles and better reflection properties, which ultimately leads to precise and reliable measurement results. Therefore, UWT’s free-radiating radar sensors also work with 80 GHz technology.

Guided radar sensors, on the other hand, can measure at a much lower frequency (1 GHz) due to their function, which in turn offers advantages in the case of dust, adhesions, foam, steam or moving surfaces. As a result, guided radar sensors can also be used for interface measurement. Another important component of guided radar sensors is the probe. Here, different variants are available depending on the application. UWT offers sensors with rod probes, cable probes, coated cable probes (PA) and coaxial probes in order to have the right solution for every application.

Trade Show Achema 2022
ACHEMA is the world forum for chemical engineering, process engineering and biotechnology. Every three years the world’s leading show for the process industry attracts around 3,800 exhibitors from over 50 different countries to present new products, processes and services to 150,000 professionals from all over the world. The spectrum ranges from laboratory equipment, pumps and analytical devices to packaging machinery, boilers and stirrers through to safety technology, materials and software, thus covering the entire needs of the chemical, pharmaceutical and food production industries. The accompanying congress, featuring 800 scientific lectures and numerous guest and partner events, complements the wide range of themes of the exhibition. Focal topics are identified anew for every ACHEMA and feature topics that are currently trending in industry. In 2021, they are - The digital lab: In the lab data from every stage of research and production converge. Modularly designed and fully connected, the digital lab is a data mine for process design and quality control. - Product and process security: The interfaces between the real and the virtual world demand special attention in times of industry 4.0 and Internet of Things. - Modular and connected production: A fully connected value chains makes faster product cycles possible as well as small batches of specialized products. Based on the proven ACHEMA concept with its unique range of topics and the established interplay of exhibition and congress, the organizers at Dechema are currently working on new formats that will offer even more opportunities for discussion and networking. These include matchmaking tools as well as new interactive event formats. They are intended to stimulate discussion and provide additional impulses. The hall layout has also been slightly adapted to make optimum use of the structural changes on the exhibition grounds and to integrate the brand new Hall 12, located right in the center. Thus ACHEMA, which celebrates its centenary in 2020, offers the opportunity to truly experience the latest solutions and products for the process industry and to make global contacts.
