Level Sensors
A guided wave radar level sensor utilising VEGA VEGAFLEX technology uses microwave pulses which are conducted along a cable or rod measuring probe. The measuring probe of the level sensor ensures that the signal reaches the medium undisturbed. The pulse signal is reflected by the mediums surface and is received by the processing electronics. This information is then used and converted into level information.
Level Sensors
The level of almost any liquid or solid can be measured using VEGA guided wave radar sensors. Guided radar is virtually unaffected by changes to product or process temperature, pressure, density, conductivity, vapours, build up or dust. No moving parts mean the radar level sensors are extremely reliable and eliminates the need for recalibration.
All guided wave radar sensors have built in linearisation software to calculate the level versus shape and provide direct output of volume on:-
VEGA are the worlds’ No.1 process radar manufacturer, with the experience of over 200,000 successful installations. In 1997 VEGA introduced the first two wire, loop powered radar to the market and are the established leaders in this field.
VEGAFLEX series of guided wave radar level sensors are usually mounted from the top. Calibration is easy and uses a small entry to the vessel (from ¾” BSP). VEGAFLEX is part of the plics® family:
