Check properties
Before installing your
mini CORI-FLOW ML120
, check the label on the rear side of the instrument to
see if the functional properties match your requirements:
·
Flow rate
·
Fluid to be measured
·
Up- and downstream pressures
·
Temperature
·
Valve type (NO= Normally Opened)
·
Input/output signal (see also
)
The Lab-style instrument housing is rated at IP40.

Check operating conditions
2.2.1
Tested pressure
Each CORI-FLOW is pressure tested to at least 1.7 times the working pressure of the process conditions provided by the
customer, with a minimum of 340 bar(a) for meters and 8.5 bar(a) for controllers. Each instrument is helium leak tested to at
least 2*10
-9
mbar l/s Helium outboard.
The tested pressure is stated on the instrument with a red sticker. Check this test
pressure before installing the instrument in the application. If the sticker is not
available or the test pressure is incorrect, the instrument should
not
be mounted
in the process line and be returned to the factory.
The tested pressure should always be higher than the maximum operating
pressure.

Sealing material
mini CORI-FLOW ML120 instruments are equipped with specific sealing material(s), compatible with the media specified
at ordering time. Be sure that the sealing materials are compatible with the media and conditions used in the system. Do
not exceed the indicated maximum operating pressure and temperature. Bronkhorst High-Tech B.V. cannot be held
responsible for any damage resulting from the use of other media and/or conditions than specified at ordering time.
mini CORI-FLOW ML120V00
instruments are metal sealed.
mini CORI-FLOW ML120V21
instruments are equipped ex factory with internal sealings in the piezo-valve, compatible with
the media specified at ordering time. As a factory standard, the instruments are provided with Kalrez® (FFKM) seals.

Piping requirements
MAKE SURE THAT THE PIPING IS ABSOLUTELY CLEAN!
Particles can damage or clog the instrument. The piezo valve’s metal membrame can be seriously damaged by particles in
the fluid.
During the manufacturing process, the instruments have been tested with water. Despite the fact that the instruments have
been purged thoroughly afterward, the delivered instruments cannot be guaranteed to be absolutely free of water droplets.
Bronkhorst strongly recommends performing an additional, adequate drying procedure for those applications where
remaining water particles may cause undesired reactions such as corrosion.
