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.

Vega New Product

VEGASWING 66 is a world first. It is VEGA’s latest addition to its portfolio of vibrating limit switches
for liquids. The instrument is designed for reliable, self monitoring, fail safe switching in applications
with process temperatures up to +450 °C and process pressures up to 160 bar.

Until now, the principle of the vibrating level switch has been limited to process conditions up to a
maximum of +280 °C and 100 bar. By using a new drive for the tuning fork of VEGASWING 66, VEGA has made deployment of the instrument possible far beyond these limits. VEGASWING 66 delivers a convincing performance with impressive values: process temperatures from -196° C to +450° C and pressures from 0 to 160 bar.

Since it is virtually unaffected by product properties such as product density, the vibrating level switch
can be used with hardly any restrictions. The sensor switches reliably and reproducibly when a certain
filling level is reached. Adjustment with medium is not required for setup. The integrated analysis and
monitoring capabilities allow certification according to SIL2 and steam boiler regulations.
Versatile and dependable.

Users benefit from the technical features in combination with the total self-monitoring of the sensor
and can be sure of highest system reliability – even in critical high-temperature and high-pressure
applications. In addition, the universal level sensor VEGASWING 66 saves a lot of time and costs
through its simple setup and commissioning.

The application range of VEGASWING 66 extends from distillation columns in the oil and gas
industry, to high and low water limits in steam boilers, to cryogenic applications in gas tanks for LNG
and nitrogen.

Standard approvals according to ATEX and FM for use in explosive gases and dust, as well as
versions as compact sensor or with tube extensions up to 6 m, round out the wide application
spectrum of this unique, new product.
