Vega Level measurement
In continuous level measurement, the instantaneous level at a measuring point is detected and converted into an electronic signal. The level signal is either displayed directly on site or fed into a process control or management system. Liquids, pastes, powders and bulk solids are measured with this method.
Typical applications for continuous level measurement are process tanks, storage tanks, silos or mobile containers in the process industry, e.g. the chemical and pharmaceutical industry, as well as in environmental engineering, water and sewage systems, power generation, metal production and offshore systems.
Every industry places its own very specific demands on measurement technology. VEGA offers many different physical measuring principles for level measurement. It can provide a continuous level sensor perfectly adapted to the properties of the medium as well as the individual process conditions at the measuring point.

VEGAPULS: Contactless measurement under arduous process conditions

Measuring principle
Extremely short microwave impulses are emitted by the antenna system to the measured product, reflected by the product surface and received again by the antenna system. They spread with light velocity and the time from emission to reception of the signals is proportional to the level in the vessel. A special time spreading procedure enables the reliable and precise measurement of the extremely short times. The radar sensors work with low emitted power in the C and K-band frequency range. The proven ECHOFOX signal processing selects the correct level echo reliably from a number of false reflections. An adjustment with empty and full vessel is not necessary.

Applications in liquids
Two different emitting frequencies are available for these applications. The compact, high frequency sensors are particularly suitable for applications for which high accuracy is required. Even with small antenna sizes, an excellent signal focusing is reached. Low frequency C-band sensors can penetrate foam and strong condensation and are thus particularly suitable for arduous process conditions. Unaffected by steam, gas composition, pressure and temperature changes the sensors detect the product surface of different products reliably.

Applications in bulk solids
High frequency sensors in K-band technology are used for these applications. Thanks to the very good focusing of the signals, the influences of silo installations or buildup on the vessel wall are gated out. A high sensitivity electronics adapted to the requirements of the bulk solids measurement, enables a reliable level measurement of different products up to 70 m. The measuring principle is unaffected by strong dust generation, filling noise, air turbulence by pneumatic filling and temperature fluctuations. The application area covers applications in the food processing industry and the plastic processing up to the steel generation.

VEGASON: Contactless measurement with ultrasonics

Measuring principle
Short ultrasonic impulses in to range of 10 to 70 kHz are emitted by the transducer to the measured product, reflected by the product surface and received again by the transducer. They spread with sound velocity. The time from emission to reception of the signals is proportional to the level in the vessel. The proven ECHOFOX signal processing filters out the correct level echo reliably from a number of false reflections. An adjustment with empty and full vessel is not necessary!

Application in liquids
Sensors with frequencies between 30 and 70 kHz are used for these applications. They operate independent of product properties and are ideal for water/waste water applications and the measurement of slightly corrosive acids and lyes. Also applications in gas-Ex areas can be equipped with these sensors.

Applications in bulk solids
Sensors with frequencies between 10 to 30 kHz are used for these applications. The lower switching frequency enables a considerably better penetration of dusty atmosphere. An adjustment with medium is not necessary. For applications in dust-Ex areas, approved sensors are available.

VEGA Pressure measurement
In all areas of production and process measurement technology, not only can process or differential pressure measurement be realized with pressure instrumentation but also level, volume or mass measurement. The measured media are gases, vapours and liquids.
The measuring ranges of pressure transmitters start at a few millibar and reach up to several 100 bar. Pressure transmitters from VEGA are equipped with metallic or ceramic measuring cells and offer excellent long-term stability as well as high overload resistance.

VEGABAR Pressure measurement in gases and liquids

VEGABAR series 10

Measuring principle
The pressure measuring cell is the heart of the pressure transmitter converting the pressure into an electrical signal. This pressuredependent signal is converted by the integrated electronics into a standardized output signal. Different sensors are used for pressure measurement. The ceramic cells have the advantages of excellent longterm stability with high overload resistance. The metal cells cover higher measuring ranges and use stainless steel as diaphragm material.

Applications
The pressure transmitters are designed for pressure measurements of liquids and gases in all areas of industrial measurement technology. The available measuring ranges cover the range from -1 … 600 bar. The focus however, are smaller process fittings of ½“ and 1".

VEGABAR series 50

For standard applications
This instrument series is developed for applications in all areas of industrial measurement technique with standard requirements to accuracy and ambient conditions.
