Important safety instructions for the operation of RHE/RHM massflow-
meters
The following safety guidelines must be adhered to.
• The operation of equipment in hazardous-areas (with danger of explosion) must be carried
out under adherence to the specific local guidelines.
• The flow meters are produced for different types of use according to international standards.
The operation conditions of the equipment are identified on the name-plate and must be ad-
hered to.
• The indicated limits for ambient- and medium temperature must be maintained.
• Rapid temperature changes inside the sensor due to the measuring medium must be avoided.
Please note the references in the manual.
• The maximum permitted working pressure must not be exceeded.
Especially piston pumps can produce considerable pressure peaks.
• Please note, that abrasive media can reduce the wall thickness of the measuring pipes and
thus also reduce the maximum operating pressure.
• The construction material which comes in contact with the medium is identified on the name-
plate.
The manufacturer accepts no responsibility for the measuring instruments with respect to the
medium to be measured.
• We recommend checking the wall thickness of the measuring tubes from time to time, should
there be any doubts about the corrosion resistance of the materials in touch with the medium
• Rheonik does not assume any liability for production-stops and or consequential losses if this
is not particularly agreed on.
• Furthermore, please note, that our devices shall not be used in life-preserving facilities in
medical facilities, in utility vehicle, aircraft, water vehicles or in mining activities.
