Make sure that all parts of the instrument in contact with the measured
product, especially the sensor element, process seal and process
fitting, are suitable for the existing process conditions such as process
pressure, process temperature as well as the chemical properties of
the medium.
You can find the specifications in chapter "Technical data" in the or on
the type label.
Instruments with enamel coating should be treated very carefully and
shocks should be avoided. Unpack VEGAPULS 66 directly before
installation. Insert VEGAPULS 66 carefully into the vessel opening and
avoid touching any sharp vessel parts.
4.2 Mounting instructions
When mounting VEGAPULS 66, keep a distance of at least 500 mm
(19.69 in) to the vessel wall. If the sensor is installed in the center of
dished or round vessel tops, multiple echoes can arise. These can,
however, be suppressed by an appropriate adjustment (see chapter
"
Setup").
