b) for the cylindrical tank in the horizontal position:

„t h1” 

- the length of the left bottom of a tank (in the elliptic paraboloid shape), this 

parameter has the fixed precision - 2-decimal point,

„t h2”

 

- the length of  the middle  part of a tank in the cylindrical shape, this parameter has

  the fixed precision - 2-decimal point,

„t h3”

 

- the length of the right bottom of a tank (in the elliptic paraboloid shape), this 

parameter has the fixed precision - 2-decimal point,

„t d”

   

- the diameter of the middle part of a tank, this parameter has the fixed precision - 

- 2-decimal point,

„t Sn”

„t Sh” 

- parameters defining the length and position of the sensor used to measure 

level of liquids, gases or solids in the tank (Figure 7.1, 7.2).

„t Sn”

 

- distance between end of the sensor  and bottom of the tank, this parameter has 
the fixed precision 2-decimal point but the unit is 100 times smaller than “

t Sh

” 

(see Info below),

„t Sh”

 

- the measuring range, this parameter has the fixed precision - 2-decimal point.

The unit value of “

t Sn

” parameter is 100-fold less than the unit value of 

other parameters defining cylindrical tank, i.e. if we set value 10.00 in 

t Sh

” parameter and set value 08.00 in "

t Sn

" parameter this mean that 

value of “

t Sn

” parameter is real has 00.08 value in preserved unit of the 

t Sh

” parameter.

If we set parameters of tank in [

m

] unit (“

] unit 

respectively, see above), than displays the result the volume of the tank in

"

t Sh

" parameter may be greater than height (for vertical position) or 

diameter (for horizontal position) of the tank, which means that the total 

volume of the tank can be achieved by eg. such middle-current range, 

If the measurement value does not exceed permissible measurement 

range but displayed value exceeds range of 9999 than you can move to
