New HTG technology solves old tank gauging problems
- Texas Instruments, Inc., Johnson City, TN (US)
Since its introduction, hydrostatic tank gauging (HTG) has been applied in several key industries to solve unique tank gauging problems. Some of the more difficult applications for traditional tank gauging include liquid petroleum gas (LPG) bullet and sphere tanks, as well as asphalt and crude tanks. Because HTG performs real-time product mass and density calculations at the tank, it can provide very accurate inventory data for accounting and process control. It thus has been able to fill an information gap not previously achievable with traditional tank gauging. To review briefly the concepts of HTG technology, this paper describes a typical vertical, cylindrical tank equipped with two precise pressure probes, PT/sub 2/ and PT/sub 3/ (PT/sub 1/ is used with pressurized vessels). These pressure probes interface digitally with the microprocessor-based HTG processor unit.
