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.
