Information:
I
f the medium reaches the antenna, buildup can form on it and cause
faulty measurements later on.
T
he emitted radar pulses of VEGAPULS 62 are electromagnetic
waves. The polarisation plane is the direction of the electrical wave
component. Its position is marked on the instrument.

M ake sure that all parts of the instrument in contact with the measured
product, especially the sensor element, process seal and process
fi
tting, are suitable for the existing process conditions such as process
pressure, process temperature as well as the chemical properties of
the medium.
