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.


 

Radar
VEGAPULS
The measuring instrument sends out short microwave pulses in the direction of the medium and thus measures the distance to the surface. Advantage: the measurement is not affected by temperature, pressure or product properties.
Guided microwave
VEGAFLEX
Microwave pulses are guided along a rod or cable probe and reflected by the product surface. The probe ensures that the signal reaches the medium undisturbed.
 
 
Ultrasonic
VEGASON
This instrument emits ultrasonic pulses in the direction of the medium, which reflects them. The time required for the signals to get back to the sensor varies depending on the level. It’s the ideal solution for simple standard applications.
Capacitive
VEGACAL
The rod or cable probe and the vessel wall form the two electrodes of a condenser. When the level of the medium changes, the electrical capacitance between the electrodes also changes.
