ABB CoriolisMaster FCB400 Series - Concentration Measurement Densimass; Calculating Standard Volumes and Standard Densities of Liquids

CoriolisMaster FCB400, FCH400 CORIOLIS MASS FLOWMETER | OI/FCB400/FCH400-EN REV. E 125
Manual adjustment via the transmitter menu
For more information, please contact ABB Service or the sales
organization.
The following steps must be performed when adjusting the
erosion monitor manually:
1. The VeriMass function must be active („Device Setup /
...Transmitter / ...Feature Settings menu, parameter
‘VeriMass On / Off’).
2. In the ‘Diagnostics / ...Meter Erosion Mon.’ menu, set the
parameter ‘Control Type’ to ‘Manual’.
3. In the ‘Diagnostics / ...Meter Erosion Mon.’ menu, set the
parameters ‘Driver Output Max’ and ‘Driver Output Time’
to the required values.
Recommended settings
Driver Output Max Approx. 0.3 mA above the driver
current under normal operating
conditions
Driver Output Time Several days or weeks depending on
the application
Adjustment via Device Type Manager (DTM)
Alternatively, the automatic and manual balancing processes for
the erosion monitor can also be performed via the HART DTM on
the CoriolisMaster FCB450 / FCH450.
Note
Not all tools and frame applications support DTMs or EDDs at
the same level. In particular, optional or advanced EDD / DTM
functions may not be available on all tools.
ABB provides frame applications supporting the full range of
functions and performance.
For further information, please consult the Device Type Manager
documentation.
Concentration measurement DensiMass
The transmitter can calculate the current concentration from the
measured density and temperature using concentration
matrices.
The following concentration matrices are preconfigured in the
transmitter as standard:
• Concentration of sodium hydroxide in water
• Concentration of alcohol in water
• Concentration of sugar in water
• Concentration of maize starch in water
• Concentration of wheat starch in water
In addition, the user can enter two user-defined matrices:
• Up to 100 values with one matrix
• Up to 50 values per matrix with two matrices
Calculating standard volumes and standard densities of
liquids
If a suitable matrix is available, the DensiMass function also
allows the measured volume to be corrected for any selected
temperature.
The measured density can also be corrected for a given
temperature.
However, this is only possible when measuring liquids and after
entering an appropriate matrix.
This correction can also be performed using the default matrices
(see above).
The calculated standard volumes and standard densities can
also be issued for all other process variables.
The software ‘DensiMatrix’ is available for the easy input of the
matrix.
