Special conditions for safe use:
Enclosure contains glass & painted aluminum parts. If it is mounted in an area w here the use
of category 2G or 2D apparatus is required, it must be installed such that ignition source due
to propagating brush discharge sparks are excluded.
The actual maximum surface temperature of the equipment depends not on the equipment
itself, but on operating conditions of the process fluid/gas flow ing through the equipment.
The equipment by itself does not generate heat. Due to this reason the temperature class is
marked as a range. The maximum permitted ambient and process temperature limits can be
found in the operating instructions.
At start up especially for gas applications, ensure that the pressure is gradually increased
through the piping system. A sudden pressure spike situation may result in a fast movement
of the float w ithin the VA flow meter & the float may hit hard against the float stop.
Supply grounding connection by the process connections or earthing terminal.
