VEGA VEGAVIB 61 - NAMUR - Manual (Page 10)

4 Mounting
4 .1 General instructions
Make sure that all parts of the instrument exposed to the process, in
particular the sensor element, process seal and process fitting, are
suitable for the existing process conditions. These include above all
the process pressure, process temperature as well as the chemical
properties of the medium.
You can find the specifications in chapter "Technical data" and on the
type label.
In general, VEGAVIB 61 can be installed in any position. The
instrument only has to be mounted in such a way that the vibrating
element is at the height of the desired switching point.
Use the recommended cables (see chapter "Connecting to power
supply") and tighten the cable gland.
You can give your instrument additional protection against moisture
penetration by leading the connection cable downward in front of the
cable entry. Rain and condensation water can thus drain off. This
applies mainly to outdoor mounting as well as installation in areas
where high humidity is expected (e.g. through cleaning processes) or
on cooled or heated vessels.

Do not hold VEGAVIB 61 on the vibrating element. Especially with
flange and tube versions, the sensor can be damaged by the weight of
the instrument.
Remove the protective cover just before mounting.
The process fitting must be sealed if there is gauge or low pressure in
the vessel. Before use, check if the seal material is resistant against
the measured product and the process temperature.
