4. Installation
Only qualified personnel with the authorization of the user are allowed to carry out the
installation work. The qualified personnel have to have read and fully understood this instruction
manual and follow all instructions given therein.
The current accepted practices must always be considered during the installation.
The following points should be taken into account after completion of the installation work:
• It has to be checked whether all external supply connections really meet the requirements
specified in the technical data of the flow meter (e.g. pressure, temperature, etc.).
• The pipelines have to be flushed before the production is started.
• All external supply joints have to be checked for their safe, leakproof, and nearly stress-free
connection to the transmitter.
• The media supplied have to be cautiously adjusted to their required working pressure.
• Occurring leaks have to be removed immediately.
• All electrical lines have to be remote from the flow meter before welding work is started at
the pipeline.
The electric wiring of the voltage supply and the inputs and outputs of the control circuits has to
be carried out according to the wiring diagram.
4.1.
Installation instructions for the transmitter
Pay attention to the fact that the threaded fittings, clamps, or flanges are
correctly tightened! Otherwise, hot or caustic solutions or gasses could come
out of the gaps and clearances.
• Leaking liquids can lead to slip hazard.
• Leaking liquids have to be mopped up immediately and disposed of safely.
• If combustible liquids come out, they could cause an explosion hazardous area around that
place which has to be marked accordingly.
If the transmitter is connected to existing process lines, those lines have to be unpressurized
and free from product.
Do not omit to insert the gaskets into connections!
In case of leaking pipe connections you should check the seals.
After installation of the measuring device you should not fail to ensure optimum
earthing/grounding, if some welding work is required.
The best solution is to separate the complete measuring device from the network and to allow
an electrically conductive bridging-over of the pipe connections of a possibly large cross
section.
Lead the mass electrode of the welding device as close as possible to the welding seam in
order to avoid any stray currents within the pipe system and the measuring device!
