7 Installation of FLUXUS G709
7.1 Location
Select the measuring point according to the recommendations in chapter 5. The ambient
temperature must be within the operating temperature range of the transducers.
Select the location of the flowmeter within cable reach of the measuring point. The ambi-
ent temperature must be within the operating temperature range of the flowmeter (see
annex A, section Technical Data).
If the measuring point is within an explosive atmosphere, the danger zone and gases
which may be present have to be determined. The transducers and the flowmeter have
to be appropriate for these conditions.
Observe the safety instructions in chapter 2.
7.2 Connection of the Transducers - Connection System TS
It is recommended to run the cables from the measuring point to the flowmeter before the
connection of the transducers to avoid load on the connection points.
Overview
Attention!
The flowmeter FLUXUS G709 must be operated outside of explosive
atmospheres.
Note!
If transducers are replaced or added, the sensor module has to be
replaced or added, too (see section 7.8).
