Level gauging system of the oil tanker UNITED GRACE


The UNITED GRACE is fitted with an automatic level gauging and tank monitoring system. The pressure sensors measure absolute pressures. The sensors are hermetically sealed without ventilation to the free atmosphere. Reference is made through an additional sensor, reading the atmospheric pressure on a continuous basis. Temperature measurement is integrated in the sensors for improvement of the pressure reading accuracy as well as temperature monitoring of the cargo. Together with the advanced signal handling and computer technology, the functions included are: – level gauging in cargo, slop, ballast and fuel oil tanks; – temperature measurement in cargo, slop and fuel oil tanks; – vapour (inert gas) pressure in cargo and slop tanks; – draught measurement; – loading computer for on/offline stability and stress with load planning; – print out of cargo transfer reports; – serial line interface for communication with other systems.
