Pressure vessel for compressed gas with a computer, a display, and sensors to measure temperature and pressure and indicate amount of gas remaining

摘要

The pressure vessel for containing compressed gas has a shut-off valve in engagement with the mouth of the pressure vessel, and a pressure sensor in continuous contact with the interior of the pressure vessel, and a temperature sensor for sensing the gas temperature in the vessel. The vessel also has a programmable computer device with a display screen for calculating information on the amount of contents based on signals from the pressure and temperature sensors.
