Gas level display controller, gas level display device, and gas level display control method

A gas level display controller constructed to cause a remaining amount of a compressed gas stored in a tank to be displayed on a predetermined display device, the gas level display controller comprising:

• a mass computation module configured to calculate a mass of the compressed gas;
• and
• a display control module configured to make a remaining amount of the compressed gas displayed on the display device, based on a first calculated value obtained at a first timing by the mass computation module and a second calculated value obtained at a second timing later than the first timing by the mass computation module,
• the display control module performing display control,
• wherein under a condition that the second calculated value is smaller than the first calculated value, the display control makes the remaining amount of the compressed gas displayed on the display device, based on the second calculated value,
• under a condition that the second calculated value is not smaller than the first calculated value, when the first calculated value is greater than a difference between the second calculated value and a preset value, the display control makes the remaining amount of the compressed gas displayed on the display device, based on the first calculated value, and
• under the condition that the second calculated value is not smaller than the first calculated value, when the first calculated value is not greater than the difference between the second calculated value and the preset value, the display control makes the remaining amount of the compressed gas displayed on the display device, based on the difference between the second calculated value and the preset value.
