2. Precautions
2.1 Transportation and storage
Before transporting the unit, it is recommended to x the oat with a card-board strip in the same way as
when shipped from factory. Prevent foreign objects from entering the tube (e.g. by covering openings).
To protect the unit and especially the tube’s interior from soiling, store it only at clean and dry locations
2.2 Installation
Ambient temperature and humidity of the installation location must not exceed the specied ranges. Avoid
locations in corrosive environments. If such environments are unavoidable, ensure sufficient ventilation.
Although the RAMC features a very solid construction, the instrument should not be exposed to strong
vibration or impact stress.
Please note that the RAMC’s magnetic sensing system can be inuenced by external inhomogeneous
magnetic elds (such as solenoid valves). Alternating magnetic elds (≥ 10Hz) as well as homogeneous,
static magnetic elds (in the area of the RAMC), like the geomagnetic eld have no inuence. Asymmetric
ferromagnetic bodies of considerable mass (e.g. steel girders) should be kept at a distance of at least 250 mm
from the RAMC.
To avoid interference, the distance between two adjacent RAMC must be at least 300 mm.
2.3 Pipe connections
Ensure that the bolts of the anges are tightened properly and that the gaskets are tight.
Do not expose the unit to pressures higher than the indicated maximum operating pressure (refer to
specications).
While the system is pressurized the ange bolts must not be tightened or loosened.
