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

A gas level display controller sequentially calculates a mass of a compressed gas stored in a tank and makes a comparison between a first calculated value obtained at a first timing and a second calculated value obtained at a second timing later than the first timing. When the second calculated valu...

Zusammenfassung:	A gas level display controller sequentially calculates a mass of a compressed gas stored in a tank and makes a comparison between a first calculated value obtained at a first timing and a second calculated value obtained at a second timing later than the first timing. When the second calculated value is smaller than the first calculated value, the gas level display controller makes the remaining amount of the compressed gas in the tank displayed on a predetermined display device, based on the second calculated value. When the second calculated value is not smaller than the first calculated value, the gas level display controller makes the remaining amount of the compressed gas in the tank displayed on the predetermined display device, based on the first calculated value. This arrangement effectively prevents the display of the remaining amount of the compressed gas in the tank on the display device from including erroneous display, which indicates an increase of the gas level, regardless of no additional supply of the compressed gas into the tank.
