VEGAFLEX 81 – the new TDR sensor for liquids Some Guided wave

Guided wave radar for level and interface measurement of liquids
The next generation of VEGAFLEX TDR sensors are on their way to SMM. The new 80 series
devices combine powerful hardware, smart electronics and robust mechanics into one single unit.
VEGAFLEX 81 is the flagship for reliable level measurement in liquids.

VEGAFLEX 81 is suitable for level and interface measurement in all liquids – in slop and deck tanks
as well as in bypass tubes or standpipes. Operating in temperatures from -20 to +200° C and process
pressures from -1 to 100 bar, the sensor ensures accurate and highly reliable measurements. As a
member of the plics® family, it combines all the advantages of VEGA’s service-proven sensor
concept: available in rod, cable and coax versions.
Cost savings right from the start.

The guided wave radar sensors are delivered ready calibrated. A quick-start function guides the user
through the relevant settings in a few easy-to-follow steps. Through a simple adjustment in the
electronics, the sensor can output level or interface signals.
New features for safer operation.

The intelligent signal processing automatically detects changes in process conditions and adjusts
itself dynamically to them. This enables reliable overfill detection and dependable measurement under
difficult process conditions. The automatic probe end tracking function allows measurement of media
with a dielectric constant of less than 1.6. Integrated memories for measured values, events and echo
curves provide information on all important sensor and process conditions.
For applications in toxic or hazardous media, the guided wave radar sensors are equipped with a gastight feed-through (second line of protection).

To ensure dependable maintenance and servicing, VEGAFLEX 81 has asset management functions
based on NE 107 recommendations. In addition, diagnostic information such as measured values,
events and echo curves are permanently saved in the sensor electronics.

And of course the sensors have all necessary ship approvals such as ABS, BV, CCS, RINA, DNV,
GL, LR, NK as well as explosion protection approvals, e.g. ATEX, FM, etc.
