General Information 

1.1

 

Important Safety Instructions for operating Coriolis Flowmeters 

For RHE21 units requiring 12 to 24V DC power, the use of a properly grounded (PELV) 
supply is highly recommended. 

The use of shielded cables for all I/O signals is recommended to prevent interference 
from high level EMI. 

Only  the  specifically  designed  shielded  cable  supplied  by  Rheonik  should  be  used  to 
connect RHE Transmitters to RHM Flow Sensors.  Do not use other types of cable. 

For safety instructions regarding RHM Coriolis Flow Sensors, please refer to the RHM 
installation and startup guide manual. 

These measuring instruments are not designed for, and should not be installed in, life-
preserving systems used in the medical, motor vehicle, aircraft, water craft or mining 
industries. 

All  national  regulations  and  standards  regarding  electrical  installation  must  be 
observed! 

1.2

Additional Resources 

This  guide  is  intended  as  a  quick  reference  instruction  to  aid  the 
installation  and  startup  of  an  RHE21  Coriolis  mass  flow  transmitter 
with an RHM flow sensor and is a supplement to the documentation 
found  in  the  RHE2X  Desktop  Reference.  The  RHE2X  Desktop 
Reference and further resources are available for download from the
