The temperature coefficient sensor, as well as other sensors, is created in the unit properties on the Sensors tab. Press New and fill in the required fields. The type of sensor is Temperature coefficient, name and description is any of your choice. Unit of measurement is not obligatory. Be sure to clearly indicate the parameter that sends the temperature data.

Afterwards, switch to the Calculation Table tab and using the Wizard enter the coefficient values — the maximum and minimum temperature coefficient. Beforehand, some preliminary preparations should be done:

1. Look through the specification and find out the maximum and minimum working temperatures of your fuel level sensor. In our case they are t_max= +100 and t_min = -60°С.
   
2. Find out the nominal temperature for the reference volume, in other words the temperature which does not change fuel amount that is, does not require the use of a coefficient. In our case the value is the following: t_rated = +20°С.
   
3. Find out the density of a fuel you use (ρ). In our case it is diesel fuel, whose density is 0.89 t/m³.
   

Calculate the values of the coefficients using the following formulas:

Thus we have:

Now enter the data found for the minimum and maximum temperature values into the fields of the Calculation Table Wizard and generate a calculation table.

Note.
If the parameter sends not temperature, but, for example, voltage, then instead of the minimum, maximum, and rated temperature it is necessary to know the minimum and maximum voltage and also a rated voltage of a reference amount, and do the calculations on the basis of this data.
