Introduction
Accurate level measurement is essential for maintaining safety, efficiency, and process reliability across industrial operations. In challenging environments involving vapour, foam, condensation, turbulence, and extreme temperatures, conventional measurement technologies often struggle to deliver stable performance.
VEGA Guided Wave Radar (GWR) Level Measurement systems, represented by the trusted VEGAFLEX series, provide highly accurate and dependable continuous level and interface measurement for liquids and bulk solids in demanding industrial applications.
Using advanced Time Domain Reflectometry (TDR) technology, these instruments ensure reliable measurement even under the harshest operating conditions.
What is Guided Wave Radar Level Measurement?
Guided Wave Radar is a continuous level measurement technology that uses microwave pulses transmitted along a probe to detect the level of liquids or solids inside tanks and vessels.
The sensor sends high-frequency microwave signals through a rod, cable, or coaxial probe. When the signal reaches the product surface, part of the pulse reflects back to the sensor. The instrument then calculates the transit time of the reflected signal to determine the exact level.
For interface applications, the system can also detect multiple liquid layers with different dielectric constants.
Unlike non-contact radar systems, guided wave radar offers highly stable measurement in tanks with:
- Internal obstructions
- Narrow nozzles
- Vapour and foam
- Low dielectric media
Reliable Performance in Challenging Conditions
One of the key strengths of the VEGAFLEX series is its ability to maintain accurate readings in difficult process environments.
These sensors are engineered to perform reliably in applications involving:
- Steam and vapour
- Foam generation
- Condensation
- Product buildup
- Turbulence
- Dust and solids accumulation
This makes VEGA guided radar instruments ideal for industries where process stability and operational safety are critical.
Continuous Level & Interface Measurement
VEGA Guided Wave Radar sensors support both:
- Continuous level measurement
- Interface measurement between two liquids
This capability is especially valuable in separator vessels, storage tanks, and chemical processing applications where accurate interface detection is required.
The VEGAFLEX series delivers measurement accuracy up to ±2 mm, ensuring precise process control and inventory management.
