 The temperature coefficient is a [[cms/​units/​sensors/​sensors|sensor]] which is created on the basis of a parameter that sends the temperature/​voltage and is used to adjust the fuel level in the tank. Any liquids can be compressed and expanded depending on the ambient temperature,​ that is why the readings of fuel level sensor, especially of high volumes (for example, tanker), may seem to be incorrect without taking into account the temperature values. The temperature coefficient is a [[cms/​units/​sensors/​sensors|sensor]] which is created on the basis of a parameter that sends the temperature/​voltage and is used to adjust the fuel level in the tank.

Beforehand, some preliminary preparations should be done:
  
   - Look through the specification and find out the maximum and minimum working temperatures of your fuel level sensor. In our case they are t<​sub>​max</​sub>​ = +100 and t<​sub>​min</​sub>​ = -60°С.   - Look through the specification and find out the maximum and minimum working temperatures of your fuel level sensor.
