SCOPE OF THIS GUIDE
mini CORI-FLOW™
instruments are highly accurate instruments for measuring and controlling the mass flow rate of liquids and/or
gases, independent of fluid properties. These smart Coriolis instruments offer multiple process values as input- or output
parameters. Many parameters can be read and/or changed using analog or digital interfaces. Output parameters are: mass flow,
density, temperature, totalized mass flow, alarms. Input parameters are: setpoint (desired mass flow rate for controllers), reset
alarm/counter.

Notes for temperature considerations
After having used the
mini CORI-FLOW™ ML120
the first time at low temperature tighten the fluid adapter screws again in
order to prevent any leakage! Please note: if you do not tighten, the leaking adapter / fitting can cause damage! After the
first shrinking and tightening of the screws, no further precaution is necessary.
Note:
The maximum allowed temperature in the housing of the
mini CORI-FLOW™ ML120
is 70 °C. To check this, the
internal temperature sensor can be used. Temperature can be readout digitally via FLOW-DDE/E-8000 (FlowDDE par. 142) or
BRIGHT (local readout/control module). Make sure the temperature value readout here (=actual temperature in housing)
will not exceed 70 °C.
STARTING-UP

Check mini CORI-FLOW™ ML120 functional properties
Before installing your Mass Flow Meter/Controller it is important to
read the attached label and check:
·
Flow rate
·
Fluid to be measured
·
Up- and downstream pressures
·
Input/output signal
·
Temperature
·
Valve type
(if controller)
