Installation
3.1 Installation
Installation and setup must be carried out according to the applicable installation installation
standards (e.g. EN 60079-14) by qualified personnel trained in explosion protection.
Variable area flowmeters must be installed in such a way that
• There is no danger from mechanical impact effects.
• There are no external forces affecting the indicator part.
• The device is accessible for any visual inspections that are necessary, and can be viewed from
all sides.
• The nameplate is clearly visible.
• It can be operated from a location with secure footing.
Take special note of the installation position for the H250/H/... with horizontal flow
direction:
In order to comply with thermal parameters and measuring accuracy, flowmeters for horizontal
installation are to be installed in the pipeline so that the display is located on the side of the
measuring tube. The maximum product and ambient temperatures indicated as well as the
measuring accuracy are based on lateral installation of the display.
CAUTION!
The manufacturer is not liable for any damage resulting from improper use or use for other than
the intended purpose. This applies in particular to hazards due to insufficient corrosion
resistance and suitability of the materials in contact with product.
