Radar is the better ultrasonic

80 GHz radar technology for reliable liquid level measurement in all industries, including water and wastewater.

Radar for the price of ultrasonic

This radar level product series is especially suitable for more price-sensitive applications, like those found in the water and wastewater industry. These VEGAPULS sensors can be used in applications with either liquids or bulk solids. VEGA recently received the FM and CSA Intrinsically Safe Approvals for the VEGAPULS C21, C22, C23, 21, and 31 radar sensors.

The following VEGA instruments are now certified to NSF/ANSI/CAN 61: VEGAPULS C 21, VEGAPULS C 22, and VEGAPULS C 23 in addition to other pressure sensors and point level switches. You can find all the products with drinking water certifications here.

Advantages of radar level sensors compared to ultrasonic

Using radar technology to monitor water level in a variety of applications

When comparing radar vs. ultrasonic level sensors, radar sensors measure unaffected by temperature fluctuations, high pressures and environmental contaminations. 80 GHz radar technology is made for reliable liquid level measurement in all industries from water and wastewater to pharmaceutical.

Process and ambient influences

Radar sensors are unaffected by temperature, pressure or vacuum and provide correct readings under all environmental conditions.
Read more ...

Due to their physical measuring principle, ultrasonic sensors are exposed to considerable influences because the sound running time changes with temperature, e.g. due to solar radiation and gas composition. Even in heavy fog, wind or rain, the sound waves are additionally attenuated and the measuring range further restricted.

Dead zone and floodability

Radar sensors allow a safe measurement up to the sensor antenna, even in case of flooding.
Read more ...

Due to the process, flooding of the sensors occurs in some applications. Ultrasonic sensors are therefore often protected by mechanical flooding sleeves. However, such components can easily become contaminated and impair the reliability of the measurement. Radar sensors have no dead zone, do not require protective sleeves and measure reliably even in case of flooding.

Contamination and condensation

Radar sensors are insensitive to contamination and do not need to be cleaned.
Read more ...

In many applications, sensors struggle with buildup. Especially with ultrasonic sensors, this influences the reliability of the measurement signal and increases the dead zone. Thanks to optimized signal processing, radar sensors can suppress interference caused by buildup on the antenna system.

Reliability and accuracy

Radar sensors can also be used in confined spaces and installations.
Read more ...

Due to the high focusing of the 80 GHz technology, the radar beam can be aligned almost precisely to the medium to be measured. This means that there are no interference signals even with installations such as pipes or pumps, in narrow shafts or with deposits on walls. Compared to ultrasonic sensors, no interference signal suppression is necessary.
