The VEGAFLEX 81 is a high-precision guided wave radar (GWR) sensor designed for continuous level and interface measurement of liquids across virtually all industrial sectors Vega Vega. It is particularly valued for its ability to maintain accuracy despite challenging process conditions like vapor, foam, and condensation Siteresourcesltd Xktransmitter.

Product Overview & Key Features

Technology: Uses Time Domain Reflectometry (TDR) to send microwave pulses along a cable or rod probe, ensuring reliable signal delivery even in narrow vessels or low-conductivity liquids Fluidic-Ltd Heatingandprocess.
Versatility: Capable of measuring both total level and the interface of separation layers (e.g., oil on water) simultaneously Insatech.
Specifications: Offers measurement ranges up to 75m (cable) or 6m (rod/coax) with a high accuracy of ±2 mm. It operates in temperatures from -40 to +200 °C and pressures up to 40 bar Insatech.
Maintenance: The device is essentially maintenance-free due to its lack of moving parts and robust self-diagnostic electronics Telematic Youtube.

Market Trends & Insights

Market Growth: The industrial level sensor market is projected to reach $9.8 billion by 2030, growing at a 7.6% CAGR. This is driven by rapid automation in manufacturing, energy, and water treatment sectors Accio Accio.

VEGAFLEX 81 guided wave radar is a transmitter to monitor tank level. Entry via the top of the tank, VEGAFLEX 81 is available with three guide types for various applications. Guided wave radar technology is ideally suited to narrow vessels (stilling wells or bypass bridles) and is also suited for low conductivity (dk) applications. In addition, as with most VEGA instruments, the VEGAFLEX81 guided wave radar can be fitted with VEGA’s unique PLICSCOM display. This clip in display allows some setup features along with graphical representation within the head itself. The PLICSCOM display can be removed whilst the instrument is powered and fitted to another instrument for quick setup. Additionally VEGAFLEX 81 is suitable for measurement of the liquid level in foaming applications or where there is liable product build up and heavy vapours.
