Why Choose the VEGAFLEX 86
• Advanced TDR Technology
The VEGAFLEX 86 uses Time Domain Reflectometry (TDR) to measure level and interface with high precision. It sends electromagnetic pulses along the probe and calculates the reflection time. As a result, it delivers stable and accurate readings.
• Reliable Interface Measurement
This sensor accurately detects interface layers, such as oil and water. Therefore, it is ideal for separators, storage tanks, and process vessels with multiple liquid phases.
• Designed for Extreme Conditions
The VEGAFLEX 86 performs reliably in high temperatures, high pressures, and aggressive media. Its robust design makes it suitable for harsh industrial environments.
• Flexible Probe Design
With rod and cable probe options, the sensor adapts easily to different tank sizes and installation conditions. This flexibility simplifies system design and installation.
• Low Maintenance and Long Service Life
The sensor has no moving parts, which reduces wear and maintenance needs. In addition, the stable signal processing ensures long-term reliability.
FAQ
Q: What applications is the VEGAFLEX 86 best suited for?
A: It is ideal for level and interface measurement in industries such as oil & gas, chemical processing, and power plants, especially where multiple liquid phases are present.
