Why is insulation needed here? ? ?

Oxygen flow meter with temperature and pressure compensation, as shown in the figure below: The pressure is 400 KPa and the temperature is at room temperature; why is it necessary to provide insulation at the thermometer connection? ? What is the impact on the measurement results if insulation is not used? ?
Prevent external disturbances, such as rainfall and snowfall, which have a significant impact on temperature
Isn’t the purpose of performing thermal and pressure compensation to eliminate the effects of changes in ambient temperature? Is wrapping it in insulation meant to prevent sudden changes from affecting the flow rate? Is the key the sudden, abrupt change?
What impact does not using insulation have on the measurements? If the ambient temperature is already changing, then the gas flow rate will obviously adjust itself to compensate for that temperature change.
If the temperature changes suddenly, measurement errors may occur.
