The internal material database of the transmitter contains parameters for pipe and lining materials as well as for fluids. It
can be extended with user defined materials or fluids. User defined materials and fluids will always be displayed in the
scroll lists of the program branch Parameter.
User defined materials and fluids can be stored in an integrated coefficient memory (user memory area). The coefficient
memory has to be partitioned first (see section 14.1).
The parameters of user defined materials or fluids can be entered as follows:
• as constants without extended library (see section 14.2)
• as constants or as temperature and pressure dependent functions with extended library (see section 14.3)
The material and fluids scroll lists displayed in the program branch Parameter can be arranged (see section 14.5). Short-
er scroll lists make work more effective.
14.1 Partitioning of the coefficient memory
The coefficient memory can be split into parts for the following material data:
• material parameters:
– transversal and longitudinal sound speed
– typical roughness
• fluid parameters:
– min. and max. sound speed
– kinematic viscosity
– density
For the max. number of data sets for each category of these material data see Tab. 14.1.
Tab. 14.1: Capacity of the coefficient memory
max. number of data sets occupancy of the coefficient memory in %
materials 13 97
fluids 13 97
Select Special Funct.\SYSTEM settings\Libraries\Format USER-AREA.
Press ENTER.
This error message will be displayed if the entered number of data sets for a category of
material data exceeds the capacity of the coefficient memory.
Enter the number of the user defined materials. Press ENTER.
Enter the number of the user defined fluids. Press ENTER.
The occupancy of the coefficient memory is displayed for a few seconds.
Select yes to start the partitioning. Press ENTER.
The coefficient memory is partitioned accordingly. This procedure takes a few seconds.
After the partitioning, Format USER-AREA is displayed again.
