Level Guided
Microwave Measurement
VEGA level indication with Guided Microwave
Radar transmitters or TDR (Time Domain Reflectometry).
VEGA are the worlds’ No.1 process
radar manufacturer, with the experience
of over 60,000 installations and counting!
In 1997 VEGA introduced the first two wire,
loop powered radar to the market and are
the established leaders.
VEGAFLEX Guided Microwave Radar transmitters
or TDR transmitters (also referred to as
Guided Wave Radar) are for measurement and
level indication on almost any liquid or
solid and they can also be used for interface
on some applications. Guided Radar is virtually
unaffected by changes to product or process
temperature, pressure, density, conductivity,
vapours, build up or dust. Although VEGAFLEX
is in contact, it’s almost universal
and extremely reliable. No moving parts
on a Guided Microwave system means no recalibration
is needed. All units have built in linearisation
software to calculate the level versus shape
and provide a direct output of volume on:
|
- Storage vessels
- Processing and manufacturing of products
- Level indication in Silo’s and
Hoppers
- Interfaces on some liquids
|
Chemical, Pharmaceutical, Oil and Gas, Food,
Dairy, Beverage, Paper, Automotive, Aggregates,
Steel, Water and Waste Water and Marine…
and many others - just ask us for details

VEGAFLEX TDR, Guided Radar Microwave, is
usually mounted from the top. It’s
extremely easy to calibrate and uses a very
small entry to the vessel (from ¾”
BSP) this saves cost and time in both installation
and set up. VEGAFLEX is part of the plics®
family:
|
- Uses plics® platform
for uniform design, feel and operation
- Make selection easier, for faster ordering
and delivery
- Simple set up, faster commissioning,
saves you time and money
- Trend and data logging on in head display,
PLICSCOM for real time analysis
- Echo pictures in head offer performance
evaluation without laptops
- Cost of purchase and ownership among
the lowest in its class.
|
- Measuring range up to 60 m and can measure
very close to the sensor
- High resolution, high security of measurement
– unaffected by dust, vapours and
build up
- Built-in echo curve, data logging and
trend on the local display
- 4…20 mA two-wire sensors (loop
powered)
- Sensors with digital data transmission
(Profibus and FF)
|
 |
- Unaffected by product: changing density,
conductivity, moisture, dielectric constant
etc.
- No influence from surface reflections,
such as agitation, foam or angle of repose
from solids
- On solids and powders, filling clouds/dust
and obstructions that cause many non-contact
systems to mis-read are no problem either
|
VEGAFLEX transmits microwave radar pulses,
which are ‘guided’ along the
surface of a rod or cable suspended from
top to bottom of a vessel. These ‘doughnut’
shaped pulses travel in a field of around
400mm diameter, unless it is mounted inside
a tube or standpipe. When the pulses reach
the material surface, they are reflected
back up the guide to the sensor. The elapsed
time period between transmission and reception
of the signal (at the speed of light!) is
measured and calculated as a distance and
converted to level or volume.
