<p><P>PROBLEM TO BE SOLVED: To provide a maintenance method of a temperature detecting means or the like that highly keeps the insulation performance of a tank body in normal operations and prevents a temperature detecting means from being damaged during maintenance. <P>SOLUTION: The maintenance method is used for tank temperature detecting means 20 and 21 for detecting the temperature of a liquid stored in a tank body 11. The tank temperature detecting means 20 and 21 include a first thermistor 20 attached onto the surface of the tank body 11. An insulating material 12f is provided outside the tank body 11 and first thermistor 20, and, when the tank temperature detecting means 20 and 21 are maintained, an insulating material 17 insulating another position having almost the same temperature as that in the installation position of the first thermistor 20 in the insulating material 12f is removed to expose the surface of the tank body 11, and another second thermistor 25 other than the first thermistor 20 is attached onto the exposed region. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
