3.2 Principle of operation
The VEGAPULS 66 is a radar sensor for continuous level measure-
ment of liquids under difficult process conditions. It is suitable for
applications in storage tanks, process vessels or standpipes. The
instrument can be used universally thanks to the different antenna
versions.
The version with horn antenna is particularly suitable for the meas-
urement of liquids and bulk solids under extremely difficult process
conditions such as buildup, condensation and foam generation as
well as strong product movement.
With the version without antenna, the antenna system is formed in
conjunction with a measuring tube (surge or bypass tube). This ver-
sion is particularly suitable for measurement of solvents and liquid
gases.
The instrument can be used with products with an ε
r
value ≥1.8. The
actually achievable value depends on the measuring conditions, the
antenna system, the standpipe or bypass.
