JOWA USA Tank Gauging System Key System Elements: • Metritape level sensors with optional temperature detectors • Deck Unit provides level and alarm indicators on tank top to meet USCG vapor emissions requirements • Sensor housings used to mount and protect sensors and to make cable terminations • Central conditioning unit (CCU) with integral flat screen monitor performs signal conditioning, processing and calibration Features and Benefits: • Operator can view the level and alarm status of any tank at each deck unit, eliminating the need for common “Christmas tree” alarm status indicators • Level and volume with optional temperature and inert gas pressure data • Metritape sensors use rugged resistancetape technology (FM approved for use in hazardous locations) • Sensors totally accessible from tank top • Flexible Metritape sensors follow the contour of J-shaped ballast tanks • DeckMaster IV’s program derives the vertical level when stillpipes are curved. It can also compensate for list and trim manually or automatically when draft sensors are included • Cargo dedicated, but can also support ballast, service and draft • Sensors can be mounted in pairs with only one deck penetration to satisfy Independent High Alarm regulations • Slave deck units may be connected for usage at cargo manifolds • Optional RS 232 / 485 interface to customer system
