User Manual For - CONTROLLER/DATA RECORDER MultiCon CMC-99/141
Errors in file:
The device before saving the file in its internal memory validates the data. Lack of the
heading will be detected by the device and during saving to the internal memory the device
will add heading as follows: “Input”;”Output” without modifying the source file. Next the device
checks value ranges (absolute value of the parameters has to be in closed range <
10
6
,

separators (see description above), number of coefficients
X
and
Y
(maximal of 20) and
repeating lines (which will not be loaded). Each error will be detected and displayed in order
to correct it by the user.

Task:
Let's assume that we have a water tank as in
. The task is to create a file with
user characteristic, which shows amount of water in the tank depending on the dipping of
the probe. Dimensions shown in the figure are scaled in meters.
Fig. 7.23. Example of the tank in shape of combined cylinder and cone
Solution:
Remembering that user characteristic has maximal 20 points, the user has to choose
an optimal locations of the probe in the tank, which should be considered in the characteristic.
Knowing that the value of a cylinder is changing linearly with its hight, we are calculating the
volume of the tank with highest position (0 m of immersion) and in the place where the
cylindrical and cone parts of the tank are connected (5 m of immersion). All points of
characteristic that are left, divide into equal parts between 5 and 6 meters. Knowing formulas
for volume of a cylinder and a truncated cone we can now calculate a volume of water in the
tank depending on the probe immersion. The results of these calculations and example of
