Huynh Bang is the Exclusive Sales Agent and official VEGA Representative for Vietnam and offers various measuring principles for continuous level measurement.
Level measurement
In continuous level measurement, the instantaneous level at a measuring point in a process vessel 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, such as the chemical and pharmaceutical industries, as well as in environmental engineering, water and sewage systems, power generation, metal production and offshore systems.
Every industry places its own specific demands on measurement technology. VEGA offers many different physical measuring principles for level measurement. VEGA provides 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. 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. This is the ideal solution for simple standard applications.
Hydrostatic
VEGAWELL 52 / VEGABAR 66, 67
A measuring cell at the vessel bottom detects slight changes of the hydrostatic pressure which varies dependent on the level.
Radiation-Based
Instrument series PROTRAC
The rays emitted by the gamma source are damped when penetrating the medium. A sensor on the opposite side of the vessel detects the radiation and calculates the measured value out of the radiation strength.
