Abstract
An improved fluid system and method of monitoring fluid volume in a supply cylinder is provided. A pressure regulator is disposed immediately downstream from a shutoff valve associated with the supply cylinder. A meter or gage is then positioned downstream of the regulator to monitor outlet or downstream pressure. The fluid volume in the supply cylinder upstream of the regulator is then determined by means of a modified gage. A data processor and pressure transducer may also be associated with the system to monitor other parameters or provide further information related to system performance.
