VEGAFLEX: Universial sensors for bulk solids and liquids

Measuring principle
High frequency microwave pulses are coupled on a cable or rod and guided along the probe. The pulse is reflected by the product surface and received by the processing electronics. This electronics evaluates the echo signal and converts it into a level information. All instruments are preset to the ordered probe length. The shortenable cable and rod versions can be adapted to the individual conditions on site.

Applications in liquids

Density fluctuations, steam generation or strong pressure and temperature fluctuations do not influence the measuring result. Also buildup on the probe or the vessel wall do not influence the measurement. An ideal application is level measurement in a bypass tube where even products with dielectric values below 1.6 can be measured reliably. Also connection tubes – bypass tubes have no influence.

Application in bulk solids

Typical problems in bulk solids such as e.g. dust and noise generation or condensation do not influence the reliability. Also the shape of the material cone or the product properties, e.g. the change from dry to wet sand do not influence the measuring result. Since the instruments are already preadjusted, setup is limited to connection of the sensor.

Interface measurement in liquids

The measuring principle was developed for detection of the interface. Typical applications are measurements of oil and solvents on water. The microwave impulse is reflected a second time on an interface with different dielectric value. This allows the detection of a second level. The advantage against displacers or floats is that the measuring principle is independent of density and does not use any moving parts. Through the digital communication interfaces or connection of a VEGAMET 625, the output of both levels is possible.
