5. Commissioning, operation
The measuring line should be designed and installed so that the loads occurring
due to expansion, vibration and thermal effects can be absorbed. With gaseous
media, a drain should be provided at the lowest point; with liquid media, a vent
should be provided at the highest point.
The measuring instruments must be mounted in the common mounting position
per EN 837-1, with a max. permissible incline of 5° on all sides.
