The Isothermal Map Screen presents spatial temperature information as a series of
isothermal lines and is color-
In History mode, TMS-

The system will then calculate and graphically display the average temperature within each of these zones. The Area Plot windows could be circular and rectangular. Area plots are especially useful for plant control systems such as a DCS.
TMS-
The
following statistical data may be displayed: Mean Temperature, Standard Deviation,
Rate of Change, Minimum Temperature, Maximum Temperature, Threshold Temperature and
the Time Over Temperature.
Statistics may be displayed for the current day or any
previous day with a user selectable statistical period of one hour up to twenty-
The path screen displays the locations of the Model 3020TR acoustic transceivers
around the perimeter of the mapping plane and all of the available paths in the mapping
array.
Detailed information on any path, such as transmit and receiver port numbers,
path length, and other settings are available at the Tools Menu.up to twenty-
TMS-
This window may be used to display paths that are not associated with an
isothermal map.
For example, if 20 paths are defined as making up a furnace exit
gas mapping plane, four additional paths could be defined and displayed as individual
paths in the Super-
sections of a boiler.
Path temperature graphs show up to 8 Areas and/or path temperature values. Both minimum
and maximum temperature scale values may be selected for optimum resolution of the
trace display.
Time periods may be selected from the previous 24 hour periods up
to 365 days. Each pen is color coded, any pen may be assigned to the first 8 paths
and/or areas.
It is also possible to zoom-
