The internal material database of the transmitter contains parameters for pipe and lining materials as well as for media. It
can be extended with user-defined materials or media. User-defined materials and media will always be displayed in the
scroll lists of the program branch
Parameter
.
User-defined materials and media can be stored in an integrated coefficient memory (user area). The coefficient memory
has to be partitioned first (see section 13.1).
The parameters of user-defined materials or media can be entered as follows:
• as constants without the extended library (see section 13.2)
• as constants or temperature and pressure dependent functions by means of the extended library (see section 13.3)
The material and media scroll lists displayed in the program branch
Parameter
can be arranged (see section 13.5).
Shorter scroll lists make working more efficient.
13.1 Partitioning of the Coefficient Memory
The coefficient memory can be divided into parts for the following material data:
• material parameters:
– transversal and longitudinal sound speed
– typical roughness
• medium parameters:
– min. and max. sound speed
– kinematic viscosity
– density
• heat flow coefficients (additional medium parameter)
• steam coefficients (additional medium parameter)
For the max. number of data sets for each category of these material data see Tab. 13.1.

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 media. Press ENTER.
Enter the number of user-defined data sets for the heat flow coefficients. Press ENTER.
Heat flow coefficients can only be entered if the transmitter has temperature inputs.
Enter the number of user-defined data sets for the steam coefficients. Press ENTER.
Steam coefficients can only be entered if the transmitter has temperature inputs.
