3.2 Principle of operation
The VEGAFLEX 83 is a level sensor with coated cable or rod probe
for continuous level or interface measurement, particularly suitable for
applications in the chemical industry.
High frequency microwave pulses are guided along a steel cable or
a rod. Upon reaching the product surface, the microwave pulses are
reected. The running time is evaluated by the instrument and output-
ted as level.
